Step-by-step explanation:
Hope this will help you dear.

the triangle is a right triangle, meaning that we can use the pythagorean theorem to find a hypotenuse that will satisfy both Rs. if we use 3 as the radius, we get the hypotenuse as 2 + 3 = 5, where one leg is 3 and one is 4.
so we know that a radius of 3 is right
Note that the expression is the difference of squares.
36 - 9m² = 6² - (3m)²
6² - (3m)² = (6 + 3m) (6 - 3m)
for c it would be 1\8
for E it would be 3\8
Answer: -4
