Answer:
The graph in the attached figure
Step-by-step explanation:
we have

Remember that the denominator cannot be equal to zero
so
The value of x cannot be equal to x=-2
<em>Simplify the numerator</em>
----> by difference of squares
substitute

simplify

The domain is all real numbers except the value of x=-2
The y-intercept is the point (0,-6) ---> value of y when the value of x is equal to zero)
The x-intercept is the point (2,0) ---> value of x when the value of y is equal to zero)
therefore
The graph in the attached figure

Answer:
Step-by-step explanation:
Let the width of the pool deck be x.
- Dimensions of the pool are 12 + 2x and 24 + 2x.
- Total area is 1408 ft².
<u>We have equation:</u>
- (12 + 2x)(24 + 2x) = 1408
- 12*24 + 12*2x + 24*2x + (2x)² = 1408
- 288 + 72x + 4x² = 1408
- 4x² + 72x + 288 - 1408 = 0
- 4x² + 72x - 1120 = 0
- x² + 18x - 280 = 0
- x² - 10x + 28x - 280 = 0
- x(x - 10) + 28(x - 10) = 0
- (x - 10)(x + 28) = 0
1)
2)
- x + 28 = 0
- x = - 28 (discarded as negative)
Correct choice is B
