Answer: 
Step-by-step explanation:
Pythagorean theorem: 
, where a and b are the legs and c is the hypotenuse.
We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.
Since we don't know what 
is, we're going to isolate it by subtracting 81 on both sides
We have to square root both sides in order to find out b (or x in the problem).
When you put this on a calculator it would result in which is the answer d in the problem.
Answer:
y = -3
Step-by-step explanation:
So, first you need to plug in -4y-4 for x. So, 5(-4y-4) + 2y=34. Now, use the distributive property and now it will become -20y -20 + 2y = 34. Add like terms which would be -20y + 2y = -18y. Now the equation is -18y - 20 = 34. Now use inverse operations and add 20 to both sides. Then the equation will be -18y = 54. When you divide -18 on both sides, you get y=-3.
Hope this helps :)
Distance between two points
√0+49=
√49
= 7
Distance between points (3, 3) and (3, -4) is 7

To find how much fencing Jordana will need you will find the perimeter of the given shape. This includes 3 straight sides and a rounded side.
28 ft + 14 ft + 28 ft = 70 feet for the straight sides.
To find the distance around the circular side, you will need to find half of the circumference of the circle.
1/2 x pi x d
1/2 x 22/7 x 14 = 22 feet
70 feet + 22 feet = 92 feet
Jordana will need 92 feet of fencing to enclose this space.
2.5
Step-by-step explanation:
Multiply 2.5 by y and you get x
