Answer 1

Answer:

The answer is C.3(x+3)/7

Step-by-step explanation:

Answer 2

Answer:

C

Step-by-step explanation:

Factor, where possible the expressions on the numerators/ denominators

3x - 21 = 3(x - 7) ← common factor of 3

x² + 3x = x(x + 3) ← common factor of x

7x - 49 = 7(x - 7) ← common factor of 7

The rational expression can now be written as

$\frac{3(x-7)}{x}$ × $\frac{x(x+3)}{7(x-7)}$

Cancelling the factors x, x - 7 on the numerator/denominator leaves

$\frac{3(x+3)}{7}$ → C
