Give the values of a, b, and c needed to write the equation's general form. A = 2/3; B = 1; C = -20 A = 2; B = 2; C = 43 A = 2; B = 2; C = -43

See below.

Step-by-step explanation:

(a) Equation #1

Ax² + Bx + C⇒ 2/3x² + x - 20⇒ 2x² + 3x - 60

(b) Equation #2

⇒ 2x² + 2x + 43

(c) Equation #3

⇒ 2x² + 2x - 43

I’m guessing that the answer is c, but i’m not sure which grid is being talked about. since 5x5= 25 and 3x3= 9 (which there are no answers for). a is not right because while the ratio is the same, 6/25= 0.24 which is equal to 24% not 30%.
