True because I don’t actually know I just need points
Answer:

Step-by-step explanation:
We want to simplify:

The trick is that when a negative index in the numerator comes to the denominator , it becomes positive.
The vice-versa is also true.
That is:

and

We simplify to get:

The last choice is correct.
The answer is 3 because you use the same dimensions as the triangle.
Answer: 9
Step-by-step explanation:
The equation x^2 - 36 = 5x is a quadratic equation and can be solved thus: x^2 - 36 = 5x x^2 - 5x - 36 = 0 x^2 + 4x - 9x - 36 = 0 x(x + 4) - 9(x + 4) = 0 (x - 9)(x + 4) = 0 x - 9 = 0 or x + 4 = 0 x = 9 or x = -4 Therefore, the positive solution of x^2 - 36 = 5x? is 9.
