Asap plz what values of a, b, and c would you use in the quadratic formula for the following equation? 5x^2+9x=4 1. a=-4,b=9,c=5 2.a=5,b=9,c=-4 3.a=5,b=-4,c=9 4.a=5,b=9,c=4

answer: 1 + 1 = 11

step-by-step explanation:

step-by-step explanation:

let pq = qr = rs = x, and xz = y and zu = z.

if the horizontal lines are parallel, then corresponding segments are in proportion:

substitute:

therefore 3 = y = z.

xu = y + z → xu = 3 + 3 = 6
