Question

Use the gcf and the distributive property to express the sum as a product 20 35

Answer 1

Common factor of 20= 1,2,4,5,10.......
common factor of 35=1,5,7.............
so here we find that 1 and 5 r the common factors 
but the GCF of 20 and 35 is 5
so,
by using GCF the distributive property is : 5(4+7)
