Create a factorable polynomial with a GCF of 2y. Rewrite that polynomial in two other equivalent forms. Explain how each form was created.
Answer:
Hope this helps!!
Step-by-step explanation:
2ya and 2yb where a and b have no common factors and a and b are polynomaals
a=(x+2)(x+3)
b=(x+4)(x+5)
no common factors betwen a and b
so
2ya=2y(x+2)(x+3)=2yx²+10xy+12y
2yb=2y(x+4)(x+5)=2yx²+18xy+40y
the 2 polynomials are 2yx²+18xy+40y and 2yx²+10xy+12y
Answer:
The GCF of a polynomial is the greatest factor which is common to all the terms of the polynomial.
Thus, an example of a polynomial with a GCF of 2y is
The above polynomial can also be rewritten as
This form of the polynomial is obtained by factoring out the GCF of the polynomial.

Step-by-step explanation:
in a wildlife park there were 18 gray wolves after three years there were 27 gray wolves what is the precent increase
From 18 wolves to 27 wolves, what was the increase? 27 - 18 is 9, so the increase was 9.
How much of 18 is 9? 9 / 18 is equal to 1 / 2, which is 0.5. To make 0.5 a percent we multiply by 100.
0.5 times 100 is 50%.

What is the slope of the graph? (Example: 2/3,-4,-2/9)
Answer:
7/9
Step-by-step explanation:
Answer:
The slope is -1
Step-by-step explanation:
Slope is rise/run
In the picture the graph 'raises' by -1 (Because its going down) and runs by 1
so the slope is -1/1 or -1
The edges of the bases of the frustum of a regular square pyramid have length 5 and 9, and the slant height of the frustum is 6. What is the:
VOLUME OF THE FRUSTUM
SURFACE AREA OF THE FRUSTUM
I NEED HELP PLEASE PLEASE PLEASE
The volume is 201√2 and the surface area is 274.
To solve the problem, we need to calculate both the volume and the surface area of the frustum of a regular square pyramid with given dimensions.
First, let's find the volume of the frustum. The volume V of a frustum of a pyramid can be calculated using the formula:
[tex]\[ V = \frac{1}{3}h(B_1 + B_2 + \sqrt{B_1B_2}) \][/tex]
where h is the height of the frustum, [tex]\( B_1 \)[/tex] is the area of the smaller base, and [tex]\( B_2 \)[/tex] is the area of the larger base.
Given that the edges of the bases are 5 and 9, the areas of the bases are:
[tex]\[ B_1 = 5^2 = 25 \] \[ B_2 = 9^2 = 81 \][/tex]
To find the height , we can use the Pythagorean theorem on the right triangle formed by the slant height, half of the difference of the base edges, and the height of the frustum:
[tex]\[ h = \sqrt{s^2 - \left(\frac{a_2 - a_1}{2}\right)^2} \][/tex]
where s is the slant height, [tex]\( a_1 \)[/tex] is the edge of the smaller base, and [tex]\( a_2 \)[/tex] is the edge of the larger base. Plugging in the given values:
[tex]\[ h = \sqrt{6^2 - \left(\frac{9 - 5}{2}\right)^2} = \sqrt{36 - 4} = \sqrt{32} = 4\sqrt{2} \][/tex]
Now we can calculate the volume:
[tex]\[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (25 + 81 + \sqrt{25 \cdot 81}) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (106 + \sqrt{2025}) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot (106 + 45) \] \[ V = \frac{1}{3} \cdot 4\sqrt{2} \cdot 151 \] \[ V = \frac{1}{3} \cdot 604\sqrt{2} \] \[ V = 201\sqrt{2} \][/tex]
Next, let's calculate the surface area of the frustum. The surface area \( A \) of a frustum is the sum of the areas of the two bases and the area of the lateral surface:
[tex]\[ A = B_1 + B_2 + A_{\text{lateral}} \][/tex]
The lateral surface area [tex]\( A_{\text{lateral}} \)[/tex] can be found using the formula:
[tex]\[ A_{\text{lateral}} = \frac{1}{2}(P_1 + P_2)s \][/tex]
where [tex]\( P_1 \)[/tex] and [tex]\( P_2 \)[/tex] are the perimeters of the smaller and larger bases, respectively, and s is the slant height. Since the pyramid is regular and square:
[tex]\[ P_1 = 4a_1 = 4 \cdot 5 = 20 \] \[ P_2 = 4a_2 = 4 \cdot 9 = 36 \][/tex]
Now we can find the lateral surface area:
[tex]\[ A_{\text{lateral}} = \frac{1}{2}(20 + 36) \cdot 6 \] \[ A_{\text{lateral}} = \frac{1}{2} \cdot 56 \cdot 6 \] \[ A_{\text{lateral}} = 28 \cdot 6 \] \[ A_{\text{lateral}} = 168 \][/tex]
Adding the areas of the bases:
[tex]\[ A = 25 + 81 + 168 \] \[ A = 274 \][/tex]
Therefore, the volume and surface area of the frustum are:
[tex]\[ {V = 201\sqrt{2}} \] \[ {A = 274} \][/tex]

64−(3y+8y+y)÷40=37
64 - (3y + 8y + y) / 40 = 37
Simplify 3y + 8y + y
64 - 12y / 40 = 37
Add 12y / 40 to both sides and subtract 37
27 = 12y / 40
Multiply both sides by 40
1080 = 12y
Divide both sides by 12
90 = y
Answer:
y=90
Step-by-step explanation:
Collect the like terms first (3y, 8y, and y) and add them together, which gives you 12y. Equation looks like this so far 64-12y/40=37
Divide the -12 by 40, which can be reduced to -3/10.Equation so far: 64-3/10y=37
Multiply each side by 10 to cancel out the 10 in -3/10y. Equation so far: 640-3y=370
Use inverse operations to move the 640 with the 370. Equation so far: 3y=370-640
Subtract 640 from 370, which gives you -270. Then you'll have -3y=-270 and divide both sides by -3.

Answer:
[tex]5\,x\,y\,(-x+2-3y)[/tex]
Step-by-step explanation:
Always proceed by first extracting all common factors to all terms:
Notice that the factors: 5, x, and y are present in all terms, so we can extract them from the trinomial:
[tex]-5x^2y+10xy-15xy^2\\5\,x\,y\,(-x+2-3y)[/tex]
Now, the trinomial left (-x+2-3y) cannot be factored out, so then factoring is complete.

Question:
Triangle ABC is a right triangle
The length of BC is 5 units.
The area of ABC is ______ square units.
Cordinates are given below.
A(-9, 10)
B(7, -2)
C(4,-6)
Answer:
50 square units
Step-by-step explanation:
Image to question is attached.
Given:
Length of BC = 5 units
Coordinates:
A = (-9, 10)
B= (7, -2)
C = (4, -6)
Let's take BC as base, and AB as height.
Since we know length of BC, let's find length of AB.
Length of AB =
[tex] \sqrt{(-9 - 7)^2 +(10 + 2)^2 [/tex]
[tex] = \sqrt{(256)+(144) [/tex]
= 20.
Therefore, the area of triangle ABC [tex] = \frac{1}{2} b*h [/tex]
[tex] = \frac {1}{2} * 5 * 20 [/tex]
= 50 square units.

The two lines $y = 2x - 13$ and $3x+y = 92$ intersect. What is the value of $x$ at the point of intersection?
Answer:
21
Step-by-step explanation:
At the intersection of two lines, the x's are equal and the y's are equal. We may set 2x - 13 = 92 - 3x to find an x, where the y's are equal.
2x - 13 &= 92 - 3x
5x = 105
x =21

Answer:
(-1/2,1/2)
Step-by-step explanation:
We have the two endpoints
(-3,-2) and ( 2,3)
To find the x coordinate of the midpoint, add the x coordinates of the endpoints and divide by 2
(-3+2)/2 = -1/2 =-1/2
To find the y coordinate of the midpoint, add the y coordinates of the endpoints and divide by 2
(-2+3)/2 = 1/2
The midpoint is (-1/2,1/2)
