Are these numbers equivalent? 9(g+h) and 9g+9h

Hi there,

These numbers are equivalent because when you distribute 9(g+h) you get 9g+9h. which is same as the 9g+9h. Hope it helps.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
