Answer:
The answer is 3rd point.
Step-by-step explanation:
First, ypu have to move all the unrelated value to the other side :
√(4x-4) + 8 ≤ 5
√(4x-4) ≤ 5 - 8
√(4x-4) ≤ -3
Next, you have to get rid of √. In order to remove √, you have to square on both sides :
√(4x-4) ≤ -3
(√4x-4)² ≤ (-3)²
4x - 4 ≤ 9
Find the value of x by making x as a subject :
4x - 4 ≤ 9
4x ≤ 13
x ≤ 13/4
