c,-6/7=x/-14
d,-8/3=-16/x
e, x/4=-3/6
i,-40/3=-80/-x
g,30/-x=-3/2
h,-20/-7=-x/14

After being rearranged and simplified, which of the following equations could be solved using the quadratic formula? check all that apply. a. 9% + 3x2 = 14 + x-1 b. -x+ + 4x + 7 = -32-9 c. 5x + 4 = 3x4 - 2 d. 2x2 + x2 + x = 30

I'll give brainliest if you answer right : )
