Let 's x the width of the sidewalk.
Area of the swimming pool= 10*16=160 (ft²)
Area of the sideway+the swimming pool= (16+2x)*(10+2x) =160+155
==>160+20x+32x+4x²=160+155
==>4x²+52x-155=0
Δ=52²+4*4*155=5184=72²
==>x=(-52+72)/2=5/2 or x=a negative to exclude.
Width of the sideway=5/2 ft
so tell me if i helped

Answer:
If I remember the format correctly, then I think it's y=(x-1)^2-3
Step-by-step explanation:
It's a standard quadratic parabola (not stretched in any way), X coordinate of the vertex inside the parentheses (sign is opposite though), and the y coordinate outside (sign is not opposite)
Answer: 6
Step-by-step explanation:
Let's start by getting the equation to slope intercept form
First simplify
Then get y by itself
In slope intercept form y=mx+b, m is the slope
In this case the slope is 6
