Help pls or i will fail

B, 13,600

Step-by-step explanation:

First we need to figure out the whole area

to do that we do

A = L x H

plug in your numbers

A = 200 x 80 and that gives up 16,000

now we need the area of the smaller rectangular

do the same equation just with the different dimensions

A = 60 x 40 and that gives us 2,400

now subtract the 2,400 from the 16,00 to get the total area of the shaded area

13,600

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

df =

both have same length
