Answer:D

Step-by-step explanation:Multiply x and 3x to get 3x^2 which is the first part, then multiply x and -3 to get -3x then and that to 2 times 3x which get you 3x bc -3x + 6x is 3x, and for the last part, multiply 2 and -3 to get -6 so your answer will be 3x^2+3x-6

Step-by-step explanation:

Square root by factorization will be used to solve this question.

Given

$\sqrt{\frac{25}{64}}$

The square root can be applied to numerator and denominator separately

Factorization

$=\frac{\sqrt{5*5}}{\sqrt{2*2*2*2*2*2}}\\=\frac{\sqrt{5^2}}{\sqrt{2^2*2^2*2^2}}\\=\frac{5}{2*2*2}\\=\frac{5}{8}$

Hence,

Option A. 5/8 is the correct answer.
