# Find m and b: 6(2x-5) -(mx+2) = 9x+b

1 answer:

**Answer:**

m = 3; b = -12

**Step-by-step explanation:**

In order to answer the question definitively, we must assume you intend for the equation to be an identity.

6(2x -5) -(mx +2) = 9x +b

12x -10 -mx -2 = 9x +b

Equating x terms:

12x -mx = 9x

12 -m = 9 . . . . . . divide by x; next, add m-9

12 -9 =** m = 3**

Equating constant terms:

-10 -2 = b

**-12 = b**

Formula: V = PI x r^2 x H

Volume = 3.14 x 4^2 x 10

Volume = 3.14 x 16 x 10

Volume = 3.14 x 160

Volume = 160π or 502.4 units^3
