Answer:

The answer is 15

Explanation:


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

For x = 5 substitute the value of x that's 5 into the expression

We have


(4(5 + 5)(5 + 1))/((5 + 3)(5 - 3)) \\ = (4(10)(6))/(8(2)) \\ = (4(60))/(16) \\ \\ = (240)/(16)

We have the final answer as

15

Hope this helps you
