Answer:
the answer is 7
Step-by-step explanation:
7 is always right
Volume equals length times with times height
V= LwH
72=4 times 3 times H
72= 12H
Divide by 12
H= 6
distributive because you are distributing the outside number into the parentheses
W - - 3 = 18; since there is a double negative in front of 3, you can rewrite it as;
w + 3 = 18; now you need to subtract 3 from both sides to isolate the w, and your answer is w = 15
