Hello :
<span>If f(x)=x/2-2 and g(x)=2x^2+x-3, find (f+g)(x)
</span>(f+g)(x)= f(x) +g(x) = x/2-2 +2x²+x-3 = x/2 +2x²+x-5
(f+g)(x)= (x+4x²-2x-10) /2
(f+g)(x)= (4x²+3x-10)/2 = 2x²+3/2 x -5
First, we need to calculate 80% of what they earned before:
50,000 * 0.80 = 40,000 per year
Social Security = 1200 a month x 12 months ( 1 year) = 14,400 per year
Additional income = 40,000 - 14,400 = $25,600 per year
If there are x $13 each books and y $17 each books, then we can build the following equations:
x + y = 8 (or y = 8 - x)
13x + 17y = 128 (or y = 128/17 - 13x/17)

When two or more prisms have the same height, volumes are equal, because the heights are equal and the horizontal cross-sectional areas at every level are also equal.
<h3>What happens when prisms have the same height?</h3>
The volume of a prism can be found as:
= Base area x Height
This means that the volumes of two prisms with the same height will be the same because the height influences the base area which would lead to an equal measurement.
