Can someome explain to me how to write f(x)= 8x^2 - 8x +2 in vertex form?

Vertex form is f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola.

f(x) = 8x² - 8x + 2

f(x) = 8(x² - x) + 2

f(x) = 8(x² - x + 1/4) + 2 - 2

f(x) = 8(x - 1/2)²

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
