Question

1.)what is the factored form of 72x-9

2.) expand: -3(-4y-9x)

3.)simplify: 6(-5y+3)-25

4.) write an equivalent expression for 15m-3

5.) simplify: 3/4 (16g-28h)-10h

Answer 1

1.)what is the factored form of 72x-9
= 9(8x -1)

2.) expand: -3(-4y-9x)
= 12y + 27x

3.)simplify: 6(-5y+3)-25
= -30y + 18 -25
= -30y - 7

4.) write an equivalent expression for 15m-3
= 3(5m-1)

5.) simplify: 3/4 (16g-28h)-10h
= 12g - 21h - 10h
= 12g - 31h
