How many levels are in the game? You would take that number and multiply it by 0.72 to find 72% of it.
The answer would be 3z(5x + 7y)
When it tells you to find h(2), that means you plug in 2 for x.
If 2x^3 (to the third power)
2(2)^3-3
1. PEMDAS, exponents first
2^3=8
2. multiply
8x2=16
3. subtract
16-3=13
Hope this helps!
