Answer:
x = 0, x = -4, and x = 6
Step-by-step explanation:
To find the zeros of this polynomial, we can begin by factoring out a common factor of each term. 'x' is a common factor. We can distribute this variable out, giving us:
f(x) = x(x²- 2x- 24)
Now, factor the polynomial inside of the parenthesis into its simplest form. Factors of -24 that add up to -2 are -4 and 6.
f(x) = x( x + 4) (x - 6)
From this, we can derive the zeros x = 0, x = -4 and x = 6.

Answer:
Return on investment (ROI) = 7%
Step-by-step explanation:
Given:
Amount invested = $10,000
Total amount get (refund) = $10,700
Find:
Return on investment (ROI) = ?
Computation:
Amount Return = Total amount get (refund) - Amount invested
Amount Return = $10,700 - $10,000
Amount Return = $700
![Return\ on\ investment \ (ROI) = [\frac{Amount\ Return}{Amount\ invested} ]100\\\\Return\ on\ investment \ (ROI) = [\frac{700}{10,000} ]100 \\\\ Return\ on\ investment \ (ROI) =7](https://tex.z-dn.net/?f=Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7BAmount%5C%20Return%7D%7BAmount%5C%20invested%7D%20%5D100%5C%5C%5C%5CReturn%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D%20%5B%5Cfrac%7B700%7D%7B10%2C000%7D%20%5D100%20%5C%5C%5C%5C%20Return%5C%20on%5C%20investment%20%5C%20%28ROI%29%20%3D7)
Return on investment (ROI) = 7%
<span>The answer is 7 ft. The bathroom has rectangular shape. The area (A) of a rectangle is the product of the width (w) and length (l): A = w * h. The bathroom is rectangular. We know that A = 91 ft^2 and l = 13 ft. Let's substitute them in the formula for the area: 91 ft^2 = w * 13 ft. w = 91 ft^2 : 13 ft. w = 7 ft. The width of the bathroom is 7 ft.Hope this helps. Let me know if you need additional help!</span>
Answer:
(A) 21
Step-by-step explanation:
5x-15 needs to equal 90 since it is a right angle and 21 makes that true
