7(x+y)-7x
7x+7y-7x
7y is the answer
X=-6
If you divide both sides by -5 5/5 is 0 & 20/5 is 4 the next step is to subtract 2 from both sides. -4-2 is -6
Answer: 470 inches squared.
Step-by-step explanation: (15x8 + 15x5 + 8x5) x 2 = 470 inches squared
W = L - 15
WL = 76
(L-15)L = 76
L^2 - 15L - 76 = 0
(L-19)(L+4) = 0
L = 19 or -4
Since a length cannot be negative, the length must be 19 units.
The width is 19-15=4 units.
