Answer:

8(5x + 3y -7)

Explanation:

A common number in 40x+24y-56 is 8.

40x / 8 = 5x

24y / 8 = 3y

-56 / 8 = -7

We finally get 8 (5x + 3y -7)

Hope this helps!

Answer:

8 (5x +3y -7)

Explanation:

40x+24y-56


40x = 8*5*x = 2*2*2 *5*x

24y = 3*8*y = 3*2*2*2*y

56 = 7*8 = 7 * 2*2*2

As we can see, each of these terms has a greatest common factor of 8, so we can factor it out

8 (5x +3y -7)
