Answer: 22

Step-by-step explanation:

Simplify the rational expression. State any excluded values.

Answers

So on the top, you split it up using the difference of squares rule.
You get (x - 6)(x + 6) on the top.

On the bottom, you can undistribute (pull out) -7x.
This gives you -7x(x-6) on the bottom.

Now you can cancel like terms in the numerator and denominator.
You can cancel the (x-6).
You can also move the negative sign from the 7x to the (x + 6)

This leaves you with -(x + 6) over 7x, or (6 - x) over 7x.

To find excluded values, all you need to know is that you can't divide by zero under any circumstances, and you can't have a zero on the top in a rational expression.
The only values for x that would make either of these statements true are if x = 0 (7 × 0 = 0 on the bottom), or if x = 6 (6 - 6 +0 on the top)

So the answer is (6 - x) over 7x, x ≠ 0, 6

Answers

The cube of 12 is (12 x 12 x 12) = 1,728 .

The volume of a cube with side-length of 7 units is
(7 units x 7 units x 7 units) = 343 cubic units.

The volume of a cube with side-length of 14 units is
(14 units x 14 units x 14 units) = 2,744 cubic units.

The number of 1 by 1 unit cubes that would equal the volume
of the figure shown can't be determined, because the figure is
not shown.

If (7, m) is on a circle with center C(−2, 2) and radius 9, what is the value of m?

Answers

First thing I did was check the distance between the point and the center of the circle on the x-axis, because that was the information already given. Turns out that 7 - (-2) = 9, and so m is equal to the y-value of the center of the circle.

m = 2
