Don’t know how to solve.

solve the equation by graphing. x^2 +2x +1 =0
first, graph the associated parabola by plotting the vertex and four additional points, two on each side of the vertex. then, use the graph to give the solution(s) to the equation. if there is more than one solution, separate them with commas.

solution (s) : x =

Let's just put it in vertex form so we know what it is

y=x^2+2x+1

y-1=x^2+2x

y-1+1=x^2+2x+1

y=(x+1)^2

So the vertex is (-1, 0), and since the coefficient is 1 is positive this vertex is the absolute minimum for the parabola.

So plot points for x={-3,-2,0,1} to get

(-3, 4),(-2, 1),(-1, 0),(0, 1),(1, 4)

144 cm

Step-by-step explanation:

Since the shape is a square, all the lengths are the same. so to solve, add all the lengths together. Either (36+36+36+36) or 36*4. 36*4=144. So, the answer is 144 cm
