Find the area (in square feet) of a trapezoid with height h and bases b_1 and b_2. h = 6 in b_1 = 9 in b_2 = 12 in The area is _ square feet

Area of the trapezoid = 90 square feet

Step-by-step explanation:

Area of a trapezoid with bases b₁, b₂ and height h is given by the formula,

Area of a trapezoid =

By substituting the given values in the formula,

                   Area =

                            =

                            = 90 square feet

Therefore, area of the trapezoid = 90 square feet

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
