B. I'm terrible at explaining but I'm sure that's right.
Answer:
a) 44
b) 11
c) 4
Step-by-step explanation:
a) x + 46 = 90
x = 90 - 46
x = 44
b) 9x + 81 = 180
9x = 180 - 81
9x = 99
x = 11
c) (5x + 30) + 40 = 90
(5x + 30) = 90 - 40 = 50
5x + 30 = 50
5x = 50 - 30
5x = 20
x = 4

Answer:
Width=85. Length=185. Area=15,725
Step-by-step explanation:
540/2=270, which is the sum of length+width.
270-15=255, so what's left is width+width+width.
255/3=85.
85*2=170
170+15=185
85*185=15,725
