Whether -9 or 9, x^2 = 81
81 + z = 103
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!
