PLEASE HELP!!
Find the value of each variable in the parallelogram.

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

the answer is 21%.
