the length is 3W cm. THerefore, the perimeter is 2*(3W + W) = 8W = 56 So W = 7 cm.
52 + (-77) =
52 - 77 = -25
----------------------------
52 - (-77) =
52 + 77 = 129
---------------------------
your answer is: 52 - (-77)

Step-by-step explanation:
Given: 1 gallon of paint was required to create 1 mural.
