Question

Question 4 of 9Which of the following is the product of the rational expressions shownbelow?7xX - 4x+7O A x 47 - 3x – 4OB.x2x + 3x - 28C.7x²x2 + 3x - 28O D.8x2x + 3

Answer 1

Let's calculate the product:

$\frac{7x}{x-4}\cdot\frac{x}{x+7}\rightarrow\frac{(7x)(x)}{(x-4)(x+7)}\rightarrow\frac{7x^2}{x^2+3x-28}$

Therefore, the correct answer is option C.
