2(6+x) + 2x=56
12+4x=56
-12 -12
4x=44
÷4 ÷4
x=11
The measure of the width is 11ft
and the measure of the length is:
11+6=17ft

Substitue 2x for y in the second equation:

Rearrange to

form:

Factor:

Zeros are

and

To find y-coordinates of pts of intersection, plug these x-values into first equation to get

and

Vertex form:
y-k=a(x-h)^2
h=-2,k=-20,y=-12 when x=0
thus;
-12+20=a(0+2)^2
8=4a
a=2
Equation:
y+20=2(x+2)^2
y+20=2(x^2+4x+4)
f(x)=2(x^2+4x+4)-20
f(x)=2x^2+8x+8-20
f(x)=2x^2+8x-20
