Answer:
question 8 is 178cmcubed I think
Remember to follow PEMDAS, and to only combine terms with like variables.
First, distribute the 2 to all terms within the parenthesis:
2(2p + 4t) = 2(2p) + 2(4t) = 4p + 8t
3 + 4p + 8t, or (D), is your answer choice, for it cannot be simplified anymore.

12/3=4
4*15=60
60*(9)=540
540+3=543
Answer:
x=10, y=6
Step-by-step explanation:
the send equation minus the first.
(5x+y)-(3x+y)=56-36
2x=20--->x=10
then put x=10 to the first equation, 3*10+y=36, get y=6
