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

Find the integrating factor.

Multiply both sides by
.

Now the left side the derivative of a product,

Integrate both sides.

On the right side, integrate by parts.

Solve for
.

The answer will be Negative
