Question

I have no clue on how to do this someone help me out

Answer 1

15

Explanation:

Numerator ; 4(X+5)(X+1)

substitute : X=5

The first expression becomes : 4(5+5)(5+1)

= 4(10)(6)

=4×10×6

=240

Denominator : (X+3)(x-3)

substitute: X=5

=(5+3)(5-3)

=(8)(2)

=16

Now, Dividing the numerator by the denominator we have 240÷16=15

Answer 2

B

Explanation:

Substitute x = 5 into the expression

`(4(5+5)(5+1))/((5+3)(5-3))`

=
`(4(10)(6))/(8(2))`

=
`(240)/(16)`

= 15 → B
