Answer:
x = 12, sides = 23
Step-by-step explanation:

Since
is equilateral, all three sides are equal. Therefore:
![\left[\begin{array}{l}y=2x-1\\y=5x-37\\y=x+11\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dy%3D2x-1%5C%5Cy%3D5x-37%5C%5Cy%3Dx%2B11%5Cend%7Barray%7D%5Cright%5D)
Substituting y = x + 11:
![\left[\begin{array}{l}x+11=2x-1\\x+11=5x-37\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bl%7Dx%2B11%3D2x-1%5C%5Cx%2B11%3D5x-37%5Cend%7Barray%7D%5Cright%5D)
Solving for x:

Substituting x = 12:

Thus, <em>x</em> = 12 and the length of each side is 23.
Answer: Ray - begins at an endpoint and extends infinitely in one direction. Opposite Rays - have same endpoint and extend in opposite directions.
Step-by-step explanation:
C is between A and B, with AC = x, and CB = x + 6, and AB = 24
Answer: The last one.
Step-by-step explanation:
Answer:
20m^2
Step-by-step explanation:
multiply the side lengths
Answer:
C
a = 1 : b=-8; C = 12
Step-by-step explanation:
I think you did not include the sign between the x^2 and the 8x...my guess is that it is a minus.
By process of elimination the answer is not B or D bc the a-value is 1 not 0.
Then the +12 you did include in the original question indicates that the c-value is 12 not -12 eliminating answer A.
