The equivalent expressions are:

A) 16 - 4x = 4(4 - x)

B) 4x + 8 = 4(x + 2)

C) -8b - 24 = -8(b + 3)

D) 54 + 9x = 9(6 + x)

Solution:

Given that we have to write the equivalent expression

A) 16 - 4x

Take 4 as common factor out

16 - 4x = 4(4 - x)

Thus the equivalent expression for 16 - 4x is 4(4 - x)

B) 4x + 8

Take 4 as common factor out

4x + 8 = 4(x + 2)

Thus the equivalent expression for 4x + 8 is 4(x + 2)

C) -8b - 24

Take -8 as common factor out

-8b - 24 = -8(b + 3)

We can also take 8 as common factor out

-8b - 24 = 8( -b - 3)

Thus the equivalent expression for -8b - 24 is -8(b + 3) or 8(-b - 3)

D) 54 + 9x

Take 9 as common factor out

54 + 9x = 9(6 + x)

Thus the equivalent expression for 54 + 9x is 9(6 + x)
