Let b = blue ribbon and r = red ribbon.
3b/2 = r
3 * 30 / 2 = 45
r = 45
The product is C. -20. Good luck!

Answer:
(x+2)(x-5)
Step-by-step explanation:
Given the expression X^2−3x−10, we are to factorize it;
On factorizing;
= x² - 5x + 2x - 10
= x(x-5) + 2(x - 5)
= (x+2)(x-5)
Hence the factored form of the expression is (x+2)(x-5)
