Answer:
b=(14,8) A stays the same at (2,2) and C=(2,14)
Step-by-step explanation:
P = 2(L + W)
P = 112
L = 35
112 = 2(35 + W)
112 = 70 + 2W
112 - 70 = 2W
42 = 2W
42/2 = W
21 = W <=== width is 21 inches
Answer:
bro use the dang fromula
Step-by-step explanation:
L*W=A divided by 2
-8y + 9x = -5
8y + 7x = -75 +
--------------------------
/ 16x = -80
x = -80/16
x = -5
8y + 7x = -75
8y - 35 = -75
8y = -75 + 35
8y = -40
y = -40/8
y = -5
Answer : x = y = -5
