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.

Answer:
(2x - 3)(x - 2).
Step-by-step explanation:
Factor: 2x^2 - 7x + 6
Use the ac method to do this:
Multiply the leading coefficient by the last term:
2 * 6 = 12.
Now we want 2 numbers whose product is 12 and whose sum is -7.
That would be -3 and -4 so we write:
2x^2 -4x - 3x + 6
Now factor by grouping:
= 2x(x - 2) - 3(x -2)
(x - 2) is common to the 2 parts so we have:
(2x - 3)(x- 2).
Answer:
-6
Step-by-step explanation:
Add the positive numbers first which is nine then add a negative like -8 and you get then add -7 which is -6
