If you mean that the sum of the two numbers is 20 and the product is 75, then X+Y=20 and XY=75 solving for Y and substituting: Y=20-X and XY=X(20-X) then X(20-X)=75 and 20X-X2=75 (20X-X2)-(20X-X2)=75-(20X-X2) then X2-20X+75=0 factoring (X-5)(X-15)=0, so X=15 or X=5 if X=5, then Y=75/X=15 if X=15, then Y=75/X=75/15=5

Their greatest common factor is 75.

5(4x - 3)(2x + 5)

300.

15 x 11

The answer is 450. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
