A) 7(3+6)7(3+6) ​

​B) 9(4+5)9(4+5) ​

​C) 9(3+4)9(3+4) ​

D)​ 7(4+5)7(4+5) ​

Answer 1

Answer:

Option C.

Step-by-step explanation:

The given expression is

$27+36$

We need to express 27 + 36 as the product of their greatest common factor and the sum of two whole numbers with no common factor.

Factors of each term,

$27=3\times 3\times 3$

$36=2\times 2\times 3\times 3$

$GCF(27,36)=3\times 3=9$

The given expression can be rewritten as

$9\times 3+9\times 4$

Taking ou GCF,

$9(3+4)$

Therefore, the correct option is C.
