Subtract 9 from each side

15 -9 = 6x+9-9

6 = 6x

C U12122 Write a Sum or Difference as a Product A 8 Questions 1. Use the GCF to rewrite the sum as a product. 30 + 16 a) 8 (3+2)
Alex73 [517]

Answer:

<em>2(15+8)</em>

Step-by-step explanation:

Given the expression 30+16

We are to use GCF to rewrite the sum as a product.

Get the factor of each value first as shown;

30 = 2 * 15

16 = 2 * 8

substitute the factors back into the expression:

30+16 = (2*15)+(2*8)

Since 2 is common to both terms, then:

30+16  = 2(15+8)

<em></em>

<em>Hence the required sum of product of the terms is 2(15+8)</em>
