Question

expand each expression                              

3(4 w+5 )

7(2a - 7)

10(3-4d)

5(6-3y)

9(3p+5)

8(5r+3)

factor each expression

7y +21

18-12h

14-8x

12-4k

20w+ 15

24p-15

be sure

Answer 1

expand each expression3(4 w+5 )= 3*4w+3*5

7(2a - 7)= 7*2a-7*7

10(3-4d)= 10*3-10*4d

5(6-3y)= 5*6-5*3y

9(3p+5)= 9*3p+9*5

8(5r+3)= 8*5r+8*3

factor each expression

7y +21= 28y

18-12h= 2h

14-8x= 6x

12-4k= 8k

20w+ 15= 35w

24p-15= 9p
