1.
(x/2) - 7 = 11
2.
2x + 7 = 27
3.
2x - 5 = 25
Hope this helped!! (:
This situation is a right triangle with the base measuring 18 and the hypotenuse 22. We are looking for x, the height up the pole that the wire is going to be attached to. We will use Pythagorean's Theorem to find the missing length.

and

. x^2 = 160 so x =

or 12.65 feet
FORMULA:
AREA= AC x h
----------------------
2
PERIMETER= AB+BC+CA
AREA = SQUAREROOT
S(S-AB)(S-BC)(A-CA)
S= AB+BC+CA= P

Option D:

Solution:
Given compound inequality:

Let us first solve
.
Subtract 6 from both sides.


To reverse the inequality multiply by -1 on both sides.


Now solve the next inequality
.
Add 9 on both sides.


Divide by 2 on both sides.


Combine the inequality.

Option D is the correct answer.
