Answer:

Step-by-step explanation:
To add two fractions we need a common denominator. Just by looking at the two, there are no common factors. This means the denominator would be the product of the two: 4x(x-8). In order to obtain this, we multiply the first fraction by (x-8)/(x-8) - 1, and the second by 4x/4x - 1:

We can use the distributive property to simplify:

The sum of the two is:

Ah u again lol
Perimeter of Isosceles Triangle = 2x + 8
= 2(5) + 8
= 10 + 8
= 18
Therefore, the perimeter is 18. Maybe lol
