If you would like to solve for the positive value of x, you can do this using the following steps:
6 * x^2 - 54 = 0 /6
x^2 - 9 = 0
(x - 3) * (x + 3) = 0
1. x = 3
2. x = - 3
The correct result would be x = 3.
Although the problem gives the value of b, it's really not needed.
Opposite sides of a parallelogram are congruent, so we just need to calculate: 2a + 2c = P
Plug the given values in:
2 * 7.6 + 2 * 14.6 = 44.4 units, or choice (C).
