Answer:
Equation 1: x + 3y = 17
Equation 2: -x + 2y = 8
Add Equation 2 to Equation 1:
x + 3y = 17
<u>+ -x + 2y = 8</u>
5y = 25
Divide both sides by 5:
![\sf \implies \dfrac{5y}{5}=\dfrac{25}{5}](https://tex.z-dn.net/?f=%5Csf%20%5Cimplies%20%5Cdfrac%7B5y%7D%7B5%7D%3D%5Cdfrac%7B25%7D%7B5%7D)
![\sf \implies y=5](https://tex.z-dn.net/?f=%5Csf%20%5Cimplies%20y%3D5)
We can't tell until you give us its height.
Answer:
8x²+8x-2
Step-by-step explanation:
P = 2l + 2w
P = 2(4x²-x+2) + 2(5x-3)
P = 8x²-2x+4 + 10x-6
combine like terms:
P = 8x²+8x-2
