rewrite each term as a product of 7 and another term. 14f - 21 = 7 ( f ) - 7 ( ? )

Explanation:

Step1: Analyze the first - term

To rewrite $14f$ as a product of 7 and another term, divide $14f$ by 7. Since $\frac{14f}{7}=2f$, so $14f = 7(2f)$.

Step2: Analyze the second - term

To rewrite 21 as a product of 7 and another term, divide 21 by 7. Since $\frac{21}{7}=3$, so $21 = 7(3)$.

Answer:

$14f - 21=7(2f)-7(3)$
