Answer and Step-by-step explanation:
<u>The area formula for a trapezoid is as follows:</u>
A = 
Where:
A = Area
a = top side length
b = bottom side length
h = height
<u>Plug in the values given to you into the equation and solve.</u>
A = 
A = 
A = 
<u>A = 47.5 </u>
<u> is the answer.</u>

D
Step-by-step explanation:
y<2
y<x+2
y>-1/4-3
if you plug in one of the points in the included grey area the equations should be true
Domain is the numbers you can use
we can use all real numbers for this one
rangge is the numbers we get from inputting the domain
well, this is a 4th degree, so we need to find the minimum,because the leading coefient is positive so it opens up, and as x approaches negative and positive infinity, then f(x) approaches infnity
find minimum
take derivitive
f'(x)=4x^3-18x^2-8x+54
the zeroes are at about -1.652 and 1.9381 and 4.2145
we use a sign chart
the minimum occurs at hwere the derivitive changes from negative to positive
that is at -1.652 and 4.2145
evaluate f(-1.652) and f(4.2145)
f(-1.652)=-110.626
f(4.2145)=-22.124
the least value is -110.626
that is the minimum
so the domain is all real numbers
range is from -110.626 to infinity
