Question 146172: The area of a triangle is A=(1/2) * (base) * (height), where height is the perpendicular height from the apex (point on top) to the base line. If the height of a certain triangle is 7 feet longer than its base, what is the polynomial that represents its area? (Let X = the base).

The area of a triangle is A=(1/2) * (base) * (height), where height is the perpendicular height from the apex (point on top) to the base line. If the height of a certain triangle is 7 feet longer than its base, what is the polynomial that represents its area? (Let X = the base).
------------------
Let base be "x"
height is x+7
---------------
Area = (1/2)x(x+7)
Area = (1/2)(x^2+7x)
