to get the inverse of any expression, we start off by doing a quick switcheroo on the variables and then solve for "y".

Answer:
c(12 + 9 + 6)
12(2.25c)
Step-by-step explanation:
12c + 12 (3/4c) + 12 (1/2c)
12(1c) + 12(3/4c) + 12 (1/2c)
12(c + 3/4c + 1/2c)
12(2 1/4c)
12(2.25c)
Or
12c + 12 (3/4c) + 12 (1/2c)
12c + 9c + 6c
c(12 + 9 + 6)
a^2 + b^2 = c^2
9^2 + 7^2 = get the answer then find the square root of it
The aswer would be B because you have to divide a couple numbers to get 20in.
