Answer:
x=13
Step-by-step explanation:
Well, the triangle is always equal to 180 degrees in total. Lets remember that x will always be the same in every equation.
So, (5x-11) x (2x+20) x (11x-63) = 180.
Now, take away the parenthesis and add up all the like terms.
This should = 18x-54 = 180.
Now solve like you regularly would. Add 54 on both sides which equals,
18x=234. Now, divide 18 on both sides.
x = 13.
Hope this helps.

SA of a cylinder: 2
r² + 2
rh
r = radius of base
h = height of cylinder
Plug in 3 for r and 5 for h in the formula.
2
3² + 2
(3)(5)
Use a calculator to solve.
2
3² + 2
(3)(5) =
150.8 ft²
Answer:
it is 7x-4
Step-by-step explanation:
The question says that the line is parallel to the line above, so it is horizontal. When the line is horizontal it will be a 'Y=' Then, you take a look at the y axis and check to see what part of the axis the line is going through. Therefore, you can figure out that the awnser is C. I hope this explanation helps!
