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

Hope I helped.
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
