Hi,The answer to your question is down belowThe width measures 10 feet.
Let the length be x and the width be <span>x−10</span>.
Since the pool is rectangular:
<span>A=L×W</span>
<span>200=x<span>(x−10)</span></span>
<span>200=<span>x2</span>−10x</span>
<span>0=<span>x2</span>−10x−200</span>
<span>0=<span>(x−20)</span><span>(x+10)</span></span>
<span>x=20and−10</span>
A negative answer is not possible, so the width of the pool is <span><span>(20−10)</span>=10</span> feet.

x + 2 is a factor of V(x) = x³- 10x²+ 11x + 70; and x = -5 is not a possible rational zero.
<h3>What is a
cubic equation?</h3>
A cubic equation is a polynomial of degree 3.
Given the volume (V) is given by:
V(x) = x³- 10x²+ 11x + 70; where x is the length of the hot tub
a) x cannot be -5 because we cannot have a negative length, also:
V(-5) = (-5)³- 10(-5)²+ 11(-5) + 70 = -360; Also the volume cannot be negative.
b) x + 2 is a factor, hence:
x + 2 = 0
x = -2
v(-2) = (-2)³- 10(-2)²+ 11(-2) + 70 = 0
x + 2 is a factor of V(x) = x³- 10x²+ 11x + 70; and x = -5 is not a possible rational zero.

Answer: y=5x+4
Step-by-step explanation:
With the given slope and y-intercept, all we have to do is plug those values into y=mx+b. M stands for slope, and b stands for y-intercept.
y=5x+4
Answer:
x=8
Step-by-step explanation:
6(x+20)=168
6x+120=168
6x=168-120
6x=48
x=48÷6
x=8
