You would use the formula A=LW so fill in the blanks A=60 L=5 W=X. 60=5X divide 60 by 5. X=12=W. The width is 12 inches.
We are using a tool that determines the best fit line of the data points given. best fit line is projected to have the minimum standard deviation from the points.
Using the tool, the results are
<span><span>Best-fit values
</span><span>Slope-0.002667 ± 0.0006013
</span><span>Y-intercept6.475 ± 1.112
</span><span>X-intercept2428
</span><span>1/Slope<span>-375.0
Translating these results,
y = -0.00266 x + 6.475</span></span></span>
ANSWER
y=(x+3)(x-1)(x-5)
EXPLANATION
The given polynomial has x-intercepts at x=-3,x=1,x=5
These are called the zeros of this polynomial.
We can use the factor theorem to obtain the polynomial in factored form.
The polynomial in factored form is of the form
y=a(x+3)(x-1)(x-5)
The polynomial rises on the left and keep rising on the right.
This implies that, the 'a' is positive.
Therefore
y=(x+3)(x-1)(x-5)
The correct choice is the first option.
