Which of the following are solutions to the equation below? Check all that apply. 2x2 + 18 x = 20 A. 20 I B. 1 C. -2 O D. -2 E. -10 1 F. -1​

let's solve the quadratic equation :

So, there are two cases :

Case - 1 (when, 2x - 2 = 0)

Case - 2 (when, x + 10 = 0)

Therefore the required options will be :

d. it is a convex pentagon because it has five sides and none of the sides would extend into the inside of the polygon.
