Using x for width (x/2)-4=18. completely solved x=44
F(x) = 3x² - 1
f(-2) = 3(-2)² - 1
f(-2) = 3(4) - 1
f(-2) = 12 - 1
f(-2) = 11
f(x) = x < 1
f(-2) = -2 < 1
f(x) = x + 2
f(-2) = -2 + 2
f(-2) = 0
f(x) = x > 1
f(-2) = -2 > 1
f(-2) = -2 < 1
I know this one give me like 5 minutes
To make $200 a month with a 8 dollars p/h salary AFTER taxes. The simple math would just be 200/8 which would equal 25. Hope this helped!
