5x+2 - (2x - 5)
= 5x + 2 - 2x + 5
= 3x + 7
I am pretty sure that it is 3x+7
Answer:
Step-by-step explanation:
use Area=pi *
diameter is 2 * r
so r = 5
pi * = 78.5398
Area * height = volume
78.5398 * 17 = 1335.18
the cylinder holds about 1335
380
.20x = 19 + .15x
.05x = 19
x = 380
The question mark is 5. 8-5=3 and 12-5=7
