200!!!! because it’s 5x20 in each triangle and you divide by 2 so 5x20 is 100 and 100 divided by 2 is 50 and there are 4 squares so 50 x 4 and you get 200 hope that helped!!

I REALLY NEED HELP WORTH 10 POINTS URGENT!!!!!

Answer:

$(f\circ g)(4)=31$

Step-by-step explanation:

Composite Function

Given f(x) and g(x) real functions, the composite function named fog(x) is defined as:

$(f\circ g)(x)=f(g(x))$

For practical purposes, it can be found by substituting g into f.

We have:

$f(x)=3x+1$

$g(x)=x^2-6$

Computing the composite function:

$(f\circ g)(x)=f(g(x))=3(x^2-6)+1$

Operating:

$(f\circ g)(x)=3x^2-18+1$

Operating:

$(f\circ g)(x)=3x^2-17$

Now evaluate for x=4

$(f\circ g)(4)=3(4)^2-17=48-17$

$\boxed{(f\circ g)(4)=31}$
