Answer:
D. 76
Step-by-step explanation:
200x5%=10
300x7%=21
500x9%=45
10+21+45=76
The function of the trapezoid area is:
A(x)=(B+b)*h/2
Where B and b are the bases and h is the height.
With the given data: h=10 B and b =7 and x (it may vary which one is bigger)
-----------
So that function becomes:
A(x)=(7+x)*10/2
A(x)=(7+x)*5
----------
So if you want the inverse function, you have to operate to find x:
A(x)/5=7+x
A(x)/5-7=x
----------
So the new function is:
x(A)=A/5-7
The answer is C. Infinitely many because all measurements added together equals 180 degrees.
The answer is 24. To get to each term, we can see that the value is decreasing by 7. So 31 - 7 = 24
