Answer:
2xy is the greatest common factor of the three monomials.
Step-by-step explanation:
There are three monomials such that greatest common factor of first and third monomial is 2xy and greatest common factor of second and third monomial is 2x²y.
As we know greatest common factor means, common prime factors of two numbers or expressions.
Greatest common factors of 1st and second and greatest common factors of 2nd and third monomials have been given.
So, common prime factors of these two greatest common factors will be greatest common factor of all three monomials.
Prime factors of 2xy = (2)(x)(y)
Prime factors of 2x²y = (2)(x)(x)(y)
So common factors are (2)(x)(y) which is the greatest common factors of all three monomials.

Robin earned twice as much money this week as she did last week. Let d represent the amount of money she earned last week. Write a variable expression to represent how much money she earned this week? *
Answer:
2d=m
Step-by-step explanation:
d represents the amount of money she earned Last weekm represents the amount of money she earned this week2xd=m
The variable expression that represents the money Robin earned this week, if 'd' is the money she earned last week, is '2d'. This is because Robin earned twice as much this week as she did the previous week.
Explanation:In the context of this question, Robin earned twice as much money this week as she did last week. Because last week's earnings are represented by the variable, the expression to represent this week's earning becomes 2d. The number 2 is multiplied by d because Robin earned double this week of what she earned last week. Therefore, 2d accurately represents Robin's earnings for this week, if d is the amount she earned last week.

Step-by-step explanation:
Given
The inside diameter = 1/2 inches
Wall thickness = 1/16 inches
clearance = 1/32 inches
As it is given that the outside diameter is twice the thickness and diameter.
So,
Outside diameter = 1/2 + 2(1/32)
= 1/2+2/16
= 1/2+1/8
=(4+1)/8

The quantity y varies directly with the square of x and inversely with z. When x is 9 and z is 27. y is 6. What is the constant of
variation
Answer:
2
Step-by-step explanation:
Varies directly means we multiply to the constant, where as inversely means we divide the constant.
So we have
"y varies directly with the square of x and inversely with z".
This means x^2 will be on top and z will be on bottom.
Like this:
[tex]y=k\frac{x^2}{z}[/tex]
We are given x=9,z=27, and y=6. This will allow us to find k.
k is constant no matter what (x,y,z) we have.
[tex]6=k\frac{9^2}{27}[/tex]
[tex]6=k\frac{81}{27}[/tex]
[tex]6=k(3)[/tex]
Divide both sides by 3:
[tex]2=k[/tex]
So the constant of variation is 2.
Answer:
The constant of variation is 2.
Step-by-step explanation:
If y is directly influenced by x², it means that the function of y will be multiplied with x². with y being inversely influenced by z, it means that the function will be divided by z. The entire function can be written as being multiplied by an unknown factor, a:
[tex]y=a\frac{x^{2} }{z}[/tex]
Replacing the known values of x, y and z, the unknown factor, a can be calculated:
[tex]6=a*\frac{9^{2}}{27}\\6=a*\frac{81}{27}\\6=a*3\\a=2[/tex]
The constant of variation is 2.

Use the grouping method to factor the polynomial below completely.
x3 - 3x2 + 5x - 15
Answer:
[tex](x^2+5)*(x-3)[/tex]
Step-by-step explanation:
In grouping method factoring, you must have to split the middle term in a way that the product of two terms in middle must be equal to the product of two terms at the edges of equation. Remember you have to consider the resultant signs as well as the magnitude of both products.
Now in the case given above,
[tex]x^3-3x^2+5x-15[/tex]
the result is [tex]-15x^3[/tex]
Note that the magnitude is 15x^3 and sign is '-' for both products.
Now taking out the common terms, equation becomes;
[tex]x^2(x-3)+5(x-3)[/tex]
Taking out (x-3) as common, now the factorized version we have is:
[tex](x-3)(x^2+5)[/tex]

Answer:
y = 2x - 13
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2, hence
y = 2x + c ← is the partial equation
To find c substitute (4, - 5) into the partial equation
- 5 = 8 + c ⇒ c = - 5 - 8 = - 13
y = 2x - 13 ← equation of line

Angelo, Brandon, and Carl work in the same office. Angelo’s age is 4 years more than twice Carl’s age. Brandon is 5 years younger than Carl. The average of the three ages is 41.
Part A: Use a variable to define the age of one of the men.
Part B: Use the variable in part A to represent the ages of the other two men.
Part C: Write an equation that represents the average of the three men's ages equivalent to 41.
Part D: Find the age of each of the men.
Answer:
Angelo is 66 Brandon is 26 Carl is 31
Step-by-step explanation:
Variables a=Angelo b=Brandon c=Carl
Equation (1/3)(a+b+c) = 41
The age of each man is Carl (31), Angelo (66), and Brandon (26).
Explanation:Part A: Let's use the variable x to represent Carl's age.
Part B: Angelo's age is 4 years more than twice Carl's age, so we can write his age as 2x + 4. Brandon is 5 years younger than Carl, so his age is x - 5.
Part C: The average of the three ages is given as 41, so we can write the equation (x + 2x + 4 + x - 5) / 3 = 41.
Part D: To find the age of each man, we solve the equation:
(x + 2x + 4 + x - 5) = 3 * 41
4x - 1 = 123
4x = 124
x = 31
Carl's age is 31, Angelo's age is 2(31) + 4 = 66, and Brandon's age is 31 - 5 = 26.

Billboard on the highway has a perimeter of 118 feet find the length of the billboard at the height is 19 feet
Answer:
the length is 40 ft
Step-by-step explanation:
perimeter is length+length+height+height.
If the height is 19 ft then the first equation would be 118-(19+19)=80
Then you would do 80/2= 40
The length is 40 ft.
The length of the billboard with a perimeter of 118 feet and a height of 19 feet is 40 feet.
To find the length of the billboard when the perimeter is 118 feet and the height is 19 feet, you can use the formula for the perimeter of a rectangle: Perimeter = 2(length + height). Given that the height is 19 feet, you set up the equation 118 = 2(l + 19) and solve for the length (l).
First, divide both sides of the equation by 2:
59 = l + 19
Next, subtract 19 from both sides:
l = 59 - 19
l = 40

The value of the angles are the same due to them being alternate interior angles and opposite angles. This means we can set 6x-2=46. Add 2 to each side to isolate the 6x. This leaves you with 6x=48. Divide by 6 to isolate x. 48/6= 8. X=8. Hope this helps :).
If a rectangle's length is
2t+1
and the width is
t-3 write an expression for the perimeter and an expression for the area.
Answer:
Perimeter = 6t - 4
Area = 2t² - 7t - 3
Step-by-step explanation:
Given length = 2t + 1
Width = t - 3
So perimeter = 2t +1 + t - 3 + 2t + 1 + t - 3
= 2t + t + 2t + t + 1 - 3 + 1 - 3
= 6t - 4
Area = (2t + 1)(t - 7)
= 2t² - 6t + t - 3
= 2t² - 7t - 3
Sorry if im wrong but i think thats the answer
For this case we have that by definition:
The area of a rectangle is given by:
[tex]A = a * b[/tex]
Where:
a and b are the sides of the rectangle.
For its part, the perimeter will be given by:
[tex]P = 2a + 2b[/tex]
If we have as data:
[tex]a = 2t + 1\\b = t-3[/tex]
So, the area is given by:
[tex]A = (2t + 1) (t-3)[/tex]
We apply distributive property:
[tex]A=2t^2-6t+t-3\\A=2t^2-5t-3[/tex]
For its part, the perimeter is:
[tex]P = 2 (2t + 1) +2 (t-3)\\P = 4t + 2 + 2t-6\\P = 6t-4[/tex]
ANswer:
[tex]A = 2t ^ 2-5t-3\\P = 6t-4[/tex]
Is the line for the equation y = -8 horizontal or vertical? What is the slope of this
Answer:
Horizontal and it's slope is 0.
Step-by-step explanation:
y=a number is horizontal while x=a number is vertical.
The slope of horizontal lines are 0 because there is no rise.
The slope of vertical lines are undefined because there run is 0.
Slope is equal to rise over run.
y=-8 is horizontal because it represents all the points in the form (x,-8) where x is any real number.
Graph as many points as you want in the form (x,-8), you should see a horizontal line formed. The slope of y=-8 is 0.
Example of points in the form of (x,-8):
(-10,-8)
(-5,-8)
(-1,-8)
(0,-8)
(1,-8)
(5,-8)
(10,-8)
All of these go down 8 units after going left or right however many.
This is a horizontal line 8 units below the x-axis.
Answer:
Horizontal
0
Step-by-step explanation:
No matter what the x value is, the y value is - 8. Make a small table to see what that means.
x y
2 -8
0 -8
- 2 -8
See what's happening?
Look at the y intercept. The y value is - 8 when x = 0. It is also - 8 when x = 2.
Make a rough drawing on a scrap piece of paper. Plot just those 2 points. Roughly. You don't even need a ruler.
What do you see? The line must be going horizontally.
The next question is a little harder. It is not obvious, but you do know that this line either goes horizontally or vertically. So the slope can either be 0 or undefined. There is no third choice.
The general equation is y = mx + b
There is no x in y = - 8
Therefore the slope is 0. That's the only way you could get rid of the x.
Lines a and b are parallel and lines e and f are parallel.
What is the value of x?
8
82
98
172
Answer:
82
Step-by-step explanation:
Alternate exterior angles where the transversal "e" crosses parallel lines "a" and "b" are congruent. x° ≅ 82°
Answer: second option.
Step-by-step explanation:
It is important to remember that Vertical angles are defined as two non-adjacent angles formed by intersecting lines. These angles share the same vertex and they are congruent.
Observe the figure attached. Since lines "a" and "b" are parallel, you can notice that the angle 82° angle x° are Vertical angles. Therefore, they are congruent.
Then, the value of "x" is:
[tex]x=82\°[/tex]
