Substitute the values for a, b, and cinto b2 - 4ac to determine the discriminant. Which quadratic equations will have two real number solutions? (The related quadratic function will have two x-intercepts.) Check all that apply.
90=232 - 7x-9
0=x2 - 4x +4
0 0=4x2 – 3x - 1
0=x2-2x-8
D 0=332 + 5x +3

step-by-step explanation:

12.5 feet

step-by-step explanation:

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51

−3

x=17

answer:

x=17
