Question

1. What is the value of z so that -9 and 9 are both solutions of x^2+z=103?
a) -22
b) 3
c) 22
d) 184

2. What is the value of b in the triangle below? The triangle has one side that is 3b and another that is just b. The area of the triangle is 24in.^2.
a) -4 in
b) 4 in
c) no solution
d) -4 and 4

The first question is the most important, please help me with that one first. :) If you do not know the second one then do not worry about that problem. Thank you!

Answer 1

Whether -9 or 9, x^2 = 81

81 + z = 103

Answer 2

Nevermind, I understand now. Thank you. :)

Answer 3

1. C (+/-7)
2. D (no solution)
3. B (12x)
4. B (4 in)
5. C (22)

Answer 4

Thank you @chance, you are a life saver <3 <3

Answer 5

So when we're asked about finding the solution of a quadratic equation, we're supposed to find the value of x?
