I need help plssssssssss

We can say that the area of the figure equals...

5.5 by 9 rectangle - 2 by 2 triangle - 2 by 5 triangle - 9 by 3.5 triangle

5.5 by 9 rectangle = 5.5 x 9 = 49.5 un²

2 by 2 triangle = 1/2 x 2 x 2 = 2 un²

2 by 5 triangle = 1/2 x 2 x 5 = 5 un²

9 by 3.5 triangle = 1/2 x 9 x 3.5 = 15.75 un²

area of figure = 49.5 un² - 2 un² - 5 un² - 15.75 un² = 26.75 un²

answer: 26.75 un²

Andy completes the square for the equation x2 + 6x - 8 = 0. Which of the following equations reveals the vertex of the parabola?
Stolb23 [73]
If the equation x^2+6x-8 has undergo completing the square, the answer would be:
x^2+6x-8

x^2+6x+9-8-9
**In this example, since 6x is the middle term, what comes to my mind is the polynomial (x+3) because 2ab results into 6x. [from the special products lesson (a+b)^2=a^2+2ab+b^2 ] 
(x+3)^2 -17 = 0
So if the equation is equal to y, then this equation's
y+17=(x+3)^2
The vertex would be on the point (-3, -17)
