I think its a. Good luck!
Given:
- The right rectangular prism is made up of 48 cubes.
- Each cube has an edge length of 1/4 inch.

To Find:
- What is the volume of this prism?

Solution:

<u>Using formula: </u>


Substituting values in the formula:




Now,
Volume of 48 such cubes = Volume of 1 cube × 48 cubes





Hence,
- Volume of prism is <u>3/4 inch^3</u>
Well you have to find out how many cd is 40% and 30%
30% = 30x.3=9
40% = 30x.4=16
now add 16 and 9
16+9=25 now subtract 25 from 30 and see that you have 5 cd of a different type of music to find that as a % divide 5 by 35 to get .14 I rounded it to the nearest hundreth now move the decimal over 2 spots to get 14%
Simplify
9x^3 - 4x + 10 + x^3 + 10x - 9
Collect like terms
(9x^3 + x^3) + (-4x + 10x) + (10 - 9)
Simplify
<u>10x^2 + 6x + 1</u>
