The following figure is a trapezoid. the top base is 18 inches, and the bottom base is 22 inches. the height of the trapezoid is 8.5 inches. find the area of the trapezoid.

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
