Devina made a quilt using 142 pieces of fabric. She used 4 times as many fabric pieces to make a second quilt. For her third quilt, she doubled the number of fabric pieces that she used in her second quilt. How many fabric pieces did she use in the third quilt?

She used 1,136 fabrics in her third quilt

Step-by-step explanation:

For the first quilt, the number of fabrics used is 142

second quilt is 4 times this = 142 * 4 = 568 quilts

For the third quilt, she doubled the number of fabrics used

That will be 2 * 568 = 1,136 quilts

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
