Calculate the area of the shaded region using geometry. (Recall that area below the x-axis is considered negative.)
Find the area of each triangle separately. Recall that the area belowthe x-axis is negative. Add the negative and the positive regions together.
[Area of triangle A] + [Area of triangle B]
What is the value of k if the area under the cuve for 0 ≤ x ≤ k is 10? How did you obtain your solution?
[Area of triangle A] + [Area of triangle B] = 10
Simplify, and solve for k.
