Question

Write the expression below as the product of two factors.

(a + 5) + (a + 5) + (a + 5) + (a + 5)​

Answer 1

`4*(a+5)`

Explanation:

• If we add up all the terms of the expression, we have that
  `(a+5)+(a+5)+(a+5)+(a+5)=4a+20`.
• Then, if we take as common factor 4 we have that
  `4a+20=4(a+5)`.
