Answer: 42
Step-by-step explanation:
Answer:
14
Step-by-step explanation:
Since the volume of a prism is length*width*height, and the width is 3 and the height is 5 and the volume is 210, you get the equation 3x5x length=210. Solving it, you get length=14.
6(x + 2) = 2(x + 10)
6x + 12 = 2x + 20
6x - 2x = -12 + 20
4x = 8
x = 8/4
x = 2
3(y - 4) + 2 = 5y - 28
3y - 12 + 2 = 5y - 28
3y -10 = 5y - 28
3y - 5y = 10 - 28
-2y = -18
y = -18/-2
y = 9
5(2z - 3) - 3z = 3(z + 3)
10z - 15 - 3z = 3z + 9
7z - 15 = 3z + 9
7z - 3z = 15 + 9
4z = 24
z = 24/4
z = 6
