Answer:
x = 6
Step-by-step explanation:
The median is half the sum of the parallel bases , then
= 13 ( multiply both sides by 2 to clear the fraction )
12x - 46 = 26 ( add 46 to both sides )
12x = 72 ( divide both sides by 12 )
x = 6
You can find the answer using the equation (f(b)-f(a))/(b-a). For this problem, a=1 and b=3.
Then, plug in the numbers and solve:
[(3(3)^2+1)-(3(1)^2+1)]/(3-1)
=(28-4)/2
=12
