Step-by-step explanation:
2l+2w=perimeter
L is Length
W width
5(4+y) is the correct answer, you would be adding 4 and y then multiplying the sum by 5
4y:5y would be the simplest form
Answer:
x = -8.
Step-by-step explanation:
Now combine the x terms. We get x - 3y = 136 and 18x + 3y = -288.
Combining these two equations eliminates the y terms, leaving us with:
19x = -152. Solving for x, we get: x = -8. This corresponds to the second answer choice.
