Find the area of the figure and choose the appropriate result.

It's three rectangles, each with area equal to length times width.  Not rocket science.

The only slightly challenging thing is the dimensions of B.  From C we can see that the dashed side of B must be 3.8-2 = 1.8 meters.

Area = A+B+C = 4×6 + 3.5×1.8 + 3×3.8

41.7 square meters

I don't see any choices so we'll leave it here.

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

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.
