Answer:
D. Factoring trinomials
Step-by-step explanation:
The factoring trinomials method is the best way to factor the expression, since it is in the standard trinomial form ax² + bx + c
In this method, you can factor the expression by finding 2 factors of c that add up to b.
The expression is not in the simplest form, and difference of squares cannot be used because there are no perfect squares. Prime factorization is also not used for factoring expressions with variables.
So, D is the right answer.

<h2>
The simplest form of radical 
= ![\sqrt[5]{7}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7B7%7D)
.</h2>
Step-by-step explanation:
We have,
To find, the radical form of = ?
∴
We know that,
Any number raised to the power of reciprocal n is the 
root of that number.
=
∴ = [ ∵ 7 is a prime number, the simplest form of radical]
Thus, the simplest form of radical = .
Answer:
V = 105/8
Step-by-step explanation:
Volume of a box is length time width times height
V = l*w*h
= 7/2 * 5/2 * 3/2
= 105/8
