If they both have the same volume and height, they would also have the same surface area.
The answer is the distributive property
Plug the y value in
2(4)^3
Evaluate exponents first (order of operations)
2(64)
Multiply
128
Final answer: 128
The fourth choice is the correct one.
This is an expression if she only gets pedicure
y = 35
If she wants to get massage, multiply the cost for a minute with the number of minutes.
Find cost per minute first
cost = 50/20
cost = 2.5
So the expression would be
y = 35 + 2.5x
y = 2.5x + 35
