Answer:
C
Step-by-step explanation:
To find the volume of a rectangular prism, you need to multiply the width by the length by the height (the three given side lengths).
Only C and D do that. Meanwhile A and B just add them, which is not what you're supposed to do.
So, we know it's not A or B.
After finding the volume of each of the prisms, you need to add them to find the combined volume.
D multiplies them, so it's not D.
Therefore it must be C, which correctly multiplies the side lengths and then adds the volumes together at the end.
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
The following information will help us with this problem:
![\sqrt[m]{x^n} = x^{\frac{n}{m}](https://tex.z-dn.net/?f=%5Csqrt%5Bm%5D%7Bx%5En%7D%20%3D%20x%5E%7B%5Cfrac%7Bn%7D%7Bm%7D)
When we use that information in the context of this problem, we can find:
![\sqrt[4]{15^7} = 15^{\frac{7}{4}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7B15%5E7%7D%20%3D%2015%5E%7B%5Cfrac%7B7%7D%7B4%7D%7D)
Thus, a = 15, b = 7, and c = 4.
