Lera25 [3.4K]

Answer:

The required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$

Step-by-step explanation:

Given the expression

$21c+24$

Determining the factor

$21c+24$

Rewrite 24 as 3 · 8

Rewrite 21 as 3 · 7

so the expression becomes

$21c+24=3\cdot \:\:7c+3\cdot \:\:8$

Factor out the common term 3

$=3\left(7c+8\right)$

Therefore, the required answer as a product with a whole number greater than 1 will be:

$21c+24=3\left(7c+8\right)$
