ANSWER
Vertex form:

Vertex
V(-4,-11)
EXPLANATION
The given expression is

We complete the square to get the vertex form.
Add and subtract half the square of the coefficient of x.


The vertex is
V(-4,-11)
Area = Length x Width
63 = 9 x width
Width= 63 ÷ 9 = 7 feet
Answer: 7 feet
U need to find the length
7 + 7 + 18 + 18 = 50
width is 7 and length is 18
area is length x width
18 x 7 = 126 ft^2
First you must find X by setting the sides equal to each other. from that you know x=4 then plug that into the w/ they give you the Equation to. = 6then multiply by 2 and you get 12
Answer:
the darkest shaded one.
Step-by-step explanation:
because the two areas for possible answers both intersect at that area, therefore, that is the answer.
