Answer:
Step-by-step explanation:
-8( - 20+ (-4)2) = 32
-8(-20 + 16) = 32
-8(-4) = 32
32 = 32
Here, P = 2L + 2W, and L=W+55. Subbing W+55 for L in P = 2L + 2W, we get:
P = 2(W+55) + 2W = 270 in
2W + 110 + 2W = 270 in, or 4W = 160 in. Then W=40 in, and L=(40+55)in.
Let the length is x and the width is y
x - y = 4 .........(1) 2x + 2y = 12
x + y = 6........(2)
by adding 1 and 2
2x =10 , x = 5
y = 1 inch
What's the question that needs solving?
