Hello can you me out on this question posted picture

First we need to find the vertex.
Vertex of a quadratic functions exists at:

b = coefficient of x term = -4a = coefficient of squared term = 1
So,

and

Therefore, the vertex occurs at (2, -25)

x-intercepts are the points where the value of function is zero.

So,



Thus, the x-intercepts are (7,0) and (-3,0)

So option A gives the correct answer

A)26•2=52there are 2 sides with the same length116-52=64the other 2 side have to be half of 64 each64/2=32the width is 32b)make two sentences about these steps because your teacher knows how you write and explain things.
