Question

Which expression shows the sum (7 + 42) rewritten as a product of the GCF and a sum?

A. 2(3 + 17)
B. 3(2 + 14)
C. 7(7 + 42)
D. 7(1 + 6)

Answer 1

D. 7(1+6)
GCF of 7 and 42 is 7

Answer 2

The correct option is D.

Explanation:

The given expression is (7 + 42).

We need to write the given expression as a product of the GCF and a sum.

GCF of 7 and 42 is 7, because 7 is the greatest number that divides 7 and 42 completely.

Taking out the GCF, the given expression can written as

`(7+42)=7(1+6)`

The required expression is 7(1 + 6). Therefore the correct option is D.
