Area of triangle = 1/2 ab sin c
Area of triangle = 1/2 (9.2)(11.9) sin (27)
Area of triangle = 24.85 ft²
-----------------------------------------------------------------------
Answer: Area - 24.85 ft²

I think the correct answer from the choices listed above is option D. The equation that would satisfy all of the points plotted above would be y=-2x. From the plot, we can see that the y-intercept is equal to zero and by using two points we can calculate the slope to be equal to -2. Giving an equation which is y=-2x.
You have to square the binomial.
(x^3 + 4y) (x^3 + 4y)
Using FOIL:
x^9 + 4(x^3)y + 4(x^3)y + 16y^2
x^9 + 8(x^3)y + 16y^2
You could also use the formula: (a+b)^2 = (a^2 + 2ab + b^2).
(5 x 12) ÷ 2 = 30 (area of triangle)
40 x 12 = 480 (area of rectangle)
12 ÷ 2 = 6 (radius of semicircle)
3.14 x 6^2 = 3.14 x 36 = 113.04
113.04 ÷ 2 = 56.52 (area of semicircle)
30 + 480 + 56.52 = 566.52 square feet
