What is equivalent to 8x- y+ 3x?

Answer:

64

Step-by-step explanation:

You open up the (3x+5)^2 and get:

9x^2 + 30x + 25

So...

a+b+c = 64

OR

You add the coefficient(s) and the constant together in the parentheses and get:

(3x+5)^2 --> (8)^2

So you square the 8 and get:

64

Answer:

12.25 U.S. dollars

Step-by-step explanation:

Answer:

$12.25

Step-by-step explanation:

We can solve this by first finding 75% of $7. To do this, we can do $7.00 x 0.75. The product of those is 5.25. Knowing that $5.25 is 75% of $7, we are able to add up $7 and $5.25, which gives us $12.25.

Hope this helped!

Answer:

Step-by-step explanation:

hello :

given the line  :  5x – 2y = -6

the answer is : 2x + 5y = -10  because :

1) this line passes through then point (5 ,-4) : 2(5)+5(-4)=-10....right

2)  the slope of   the given line is: 5/2   because 5x-2y=-6  equivalent to ;

2y =5x+6   so : y = (5/2)x+3

On the other hand :  2x + 5y = -10 equivalent to : 5y =-2x-10

y = (-2/5)-2  when the slope is : -2/5

the condition for the perpendicularity is : product two slope is : - 1

(5/2)(-2/5) =-1

Answer:

x = 39

Step-by-step explanation:

there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two

so, (36 + 42)/2 = x

36 + 42 = 78

78/2 = 39

Answer:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

Answer:

2/3

Step-by-step explanation:

The slope is found by

m = (y2-y1)/(x2-x1)

    = (3-1)(1--2)

     = (3-1)/(1+2)

     =2/3

We can use the points (-2, 1) and (1, 3) to solve.

Slope formula: y2-y1/x2-x1

= 3-1/1-(-2)

= 2/3

Answer:

A. 25 miles per gallon

B. 225 miles

Step-by-step explanation:

Part A is asking for an average - how many miles does the car get out of each gallon. This can be found by dividing the total change in miles by the total change in gallons.

In this case, the changes in each are:

250 miles

10 gallons

250/10 is 25. Thus there are 25 miles per gallon.

Part B is asking for how much can you get with 9 gallons, meaning how many miles corresponds to 9 on the graph. The graph is at 225 miles at the x=9 mark, and thus the answer for part be is 225.

Step-by-step explanation:

Answer:

x = 100

Step-by-step explanation:

The sum of the opposite interior angles of a triangle is equal to the exterior angle

The difference between the distances from New York to Hawaii than his trip from Hawaii to Texas is 1383 miles.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Mr. Price flew 4,908 miles from New York to Hawaii. He then flew 3,525 miles from Hawaii to Texas.

Therefore, The difference between the distances from New York to Hawaii than his trip from Hawaii to Texas is,

= (4908 - 3525)  miles.

= 1383 miles.

Mr. Price's trip from New York to Hawaii was 1,383 miles longer than his trip from Hawaii to Texas.

Calculating the Distance Difference :

To find out how much farther Mr. Price's trip from New York to Hawaii was compared to his trip from Hawaii to Texas, we need to subtract the distance from Hawaii to Texas from the distance from New York to Hawaii.

Now, let's subtract the two distances:
4,908 miles - 3,525 miles = 1,383 miles

Therefore, Mr. Price's trip from New York to Hawaii was 1,383 miles longer than his trip from Hawaii to Texas.

k=11

Step-by-step explanation:

3(k - 6) = 15

Divide each side by 3

3/3(k - 6) = 15/3

k - 6 = 5

Add 6 to each side

k-6+6 = 5+6

k = 11

Answer:

k=11

Step-by-step explanation:

3(k-6) = 15

k-6 = 15/3

k-6=5

k=5+6

k=11

When x is substituted with -2 in the given expression, the value of the expression is 1.

Given the expression and the value of x, we can substitute x with -2 and evaluate the expression.  For example, if the expression is x² + 2x - 3 and you want to find the value when x = -2, then you'd substitute x = -2 into the expression giving (-2)² + 2*(-2) - 3 = 4 - 4 - 3 = -3. Substituting values in, simplifying, and solving is the general process to follow when coming across this kind of problem in quadratic equations or other areas of Algebra.

Let's say the expression is 2x + 5. Substituting x with -2, we get:

2*(-2) + 5 = -4 + 5 = 1

Therefore, the value of the expression when x = -2 is 1.

Step-by-step explanation:

The required, adjacent angle to DFE is angle BFC. Option D is correct.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Angle BFC is next to angle DFE, and they share a common side, which is line segment EF. Therefore, we can stretch this statement as follows:

"When looking at the angle DFE and moving clockwise around the vertex F, the next angle encountered is angle BFC, which is adjacent to angle DFE and shares the side EF with it."

This restatement clarifies the location and relationship of angle BFC with respect to angle DFE.

Thus, the required, adjacent angle DFE is angle BFC. Option D is correct.
