Answer:
a=4
b=6
perimiter=38
Step-by-step explanation:
you take the side lengths by it and you can subtract and stuff then you add them all up to find the perimeter
1. The absolute value function takes any quantity and makes it positive, so it's impossible to have |3x + 7| < 0. There is no solution.
2. If b + 5 ≥ 0, then
|b + 5| = b + 5 = 2b - 9
b = 14
Otherwise, if b + 5 < 0, then
|b + 5| = -(b + 5) = 2b - 9
-b - 5 = 2b - 9
3b = -4
b = -4/3
However, this second solution is extraneous, since the left side is positive,
|-4/3 + 5| > 0
while the right side is negative,
2•(-4/3) - 9 = -8/3 - 9 < 0
