Answer: C. $\frac{x-3}{3x+1}$

Step-by-step explanation:

$\frac{x+2}{x^2+5x+6}$ ÷ $\frac{3x+1}{x^2-9}$ =

$\frac{x+2}{x^2+5x+6} * \frac{x^2-9}{3x+1} = \frac{x+2}{(x+3)(x+2)} * \frac{(x-3)(x+3)}{3x+1} =$

multiply and cancel out same terms / simplify

first x+3 and x+3 cancel out

then x+2/x+2 cancels out to make 1

$\frac{x+2}{(x+2)} * \frac{(x-3)}{3x+1} = \frac{x-3}{3x+1}$

Alan is building a garden shaped like a rectangle with a semicircle attached to one short side. If he has 70 feet of fencing to

viktelen [127]

The dimension that would give the maximum area is 20.8569

<h3>How to solve for the maximum area</h3>

Let the shorter side be = x

Perimeter of the semi-circle is πx

Twice the Length of the longer side

$[70-(\pi )x -x]$

Length = $[70-(1+\pi )x]/2$

Total area =

area of rectangle + area of the semi-circle.

Total area =

$x[[70-(1+\pi )x]/2] + [(\pi )(x/2)^2]/2$

When we square it we would have

$70x +[(\pi /4)-(1+\pi)]x^2$

This gives

$70x - [3.3562]x^2$

From here we divide by 2

$35x - 1.6781x^2$

The maximum side would be at

$x = 35/2*1.6781$

This gives us 20.8569

With a fair die, the probability of rolling any number 1 through 6 is the same.

yaroslaw [1]

The probability of all possible outcomes is always 1, meaning 100%.

In this case the probability of rolling a 1,2,3,4,5, or 6 is:

1/6+1/6+1/6+1/6+1/6+1/6

6(1/6)

6/6
