For this, I will be factoring by grouping to solve for y.
Firstly, factor y^3 + 5y^2 and -9y - 45 separately, Make sure that they have the same quantity on the inside:
![y^2(y+5)-9(y+5)=0](https://tex.z-dn.net/?f=y%5E2%28y%2B5%29-9%28y%2B5%29%3D0)
Now you can rewrite it as
. However we are not finished factoring.
Now with y^2 - 9, we will apply the difference of squares rule, which is
. Apply it as such:
![(y+3)(y-3)(y+5)=0](https://tex.z-dn.net/?f=%28y%2B3%29%28y-3%29%28y%2B5%29%3D0)
Now that it is completely factored, we can apply the Zero Product Property and solve for y:
![y+3=0\\y=-3\\\\y-3=0\\y=3\\\\y+5=0\\y=-5](https://tex.z-dn.net/?f=y%2B3%3D0%5C%5Cy%3D-3%5C%5C%5C%5Cy-3%3D0%5C%5Cy%3D3%5C%5C%5C%5Cy%2B5%3D0%5C%5Cy%3D-5)
<u>In short, y = -5, -3, and 3.</u>
Answer: ![\overline{EL} \cong \overline{HP}](https://tex.z-dn.net/?f=%5Coverline%7BEL%7D%20%5Ccong%20%5Coverline%7BHP%7D)
Step-by-step explanation:
A quadrilateral with two pairs of opposite congruent sides is a parallelogram.
Answer:
y=-70
Step-by-step explanation:
10.4/10y=-28.10
4y=-280
y=-70
Answer:
C.
Step-by-step explanation:
You multiply every x in the first group of pairs and you'll get the same numbers for the second group of pairs.
Ex. (2,6) if you multiply 2 by 6 you get 12 which is the x for (12,36) then you multiply 6 by 6 you get 36 the y for (12,36)
Hope this helped.
