9(-4)/(-3)
9x-4=-36
-36/-3=12
18x-12xy+8y
You can look up the answer in an equation calculator.
That would be net A
Surface area = 13*16 + 12 * 16 + 2 (1/2*5*12) + 5*16
= 540 in^2
Answer:
3

Answer: 27
Step-by-step explanation: Every triangle has 180 degrees, if you add 3+10+7 you get 20, the ratio total is 20 and the total degrees is 180, divide 180 by 20 and you get 9, 9 x 3 (3 is the smallest of the ratios) = 27 degrees.
