Answer:
h(2) = 5.2 + 1 = 10 + 1 = 11
Volume=width times height times length
Volume=4 times 3 times 10
V=120
Subtraction of polynomials are done just as normal subtraction, but you can only subtract those with the same variables and exponents. This is shown below:
3x^2 + 8x - 7
- 5x^2 + 2x - 11
----------------------
-2x^2 + 6x + 4
