Answer:

x = 3

Step-by-step explanation:

Multiply the first equation by -1, then add it to second equation.

2x+9y = -12

-2x-7y = 8

-------------------

2y = -4

Solve for y

2y = -4

y = -2

Plug value of y into one of the equations and solve for x

2x + 9(-2) = -12

2x = 6

x = 3

(m – 6)(m + 6) is the answer.
If you distribute them, you'll get m^2 - 36

A telephone pole is installed so that 25 feet of the pole are above ground level. A stabilizing cable is anchored to the ground

Tasya [4]

$\huge\boxed{244\ \text{inches}}$

This problem can be solved using the Pythagorean Theorem.

Note: the height of the telephone pole is unnecessary information.

Convert the measurement in feet to inches.

$20*12=240$

The length from the base of the pole to the anchor point on the ground is $44$ inches. The distance from the base of the pole to the anchor point on the pole is $240$ inches.

These are the two legs of a right triangle. The length of the stabilizing cable is the hypotenuse of the right triangle.

The Pythagorean Theorem is:

$a^2+b^2=c^2$

In this formula, $a$ and $b$ are the legs and $c$ is the hypotenuse.

Plug in the known values.

$44^2+240^2=c^2$

Swap the sides of the equation.

$c^2=44^2+240^2$

Evaluate the powers.

$c^2=1936+57600$

Simplify using addition.

$c^2=59536$

Take the square root of both sides.

$c=\pm 244$

Separate the solutions.

$c=244\\c=-244$

Length and distance cannot be negative, so remove the negative solution.

$c=\boxed{244}$
