Answer :
The expression uses the greatest common factor and the distributive property to rewrite the sum 75+45 is 15(5+3)
The greatest common factor is the greatest factor that divides both numbers.
The distributive Property States that when a factor is multiplied by the sum/addition of two terms, it is essential to multiply each of the two numbers by the factor, and finally perform the addition operation
Given,
75=3×5×5
45=3×3×5
The greatest common factor = 3×5=15
Then,
(75+45)=15(5+3)
Hence, the expression uses the greatest common factor and the distributive property to rewrite the sum 75+45 is 15(5+3)
