Find the GCF and put it outside parentheses...then put the rest of digits in parentheses.

Step-by-step explanation:

1. 2a(b+c-1)

2. y^3(y^2+1)

3. 4(5x^2-3)

its not b

step-by-step explanation:

to find the perimeter of the rectangle this is the expression:

x-9+x-9+3x-4+3x-4=138

if we simplify it:

8x-26=138

remember, 138 is what it all adds up to

the length is 11.5cm

the width is 57.5cm

the area is 661.25cm^2
