Answer:
Step-by-step explanation:
Any non-parallel lines in the plane must intersect in one place; thus, there is one solution to the system of equations.
Answer:
A
Step-by-step explanation:
It's A
If a pentagon is regular, then all of the sides are the same length. This means that
![5x-4=2x+11 \iff 5x-2x = 11+4 \iff 3x=15 \iff x = 5](https://tex.z-dn.net/?f=%205x-4%3D2x%2B11%20%5Ciff%205x-2x%20%3D%2011%2B4%20%5Ciff%203x%3D15%20%5Ciff%20x%20%3D%205%20)
So, if
, the lengths of the sides evaluate to
![5x-4 = 25-4=21,\quad 2x+11=10+11=21](https://tex.z-dn.net/?f=%205x-4%20%3D%2025-4%3D21%2C%5Cquad%202x%2B11%3D10%2B11%3D21%20)
So, all the sides of the pentagon are 21 units long, and AB is 21 units long as well, because all sides are the same length.
Answer:
C = 6
D = 10
Step-by-step explanation:
C + 5 = 11
C + 5 -5 = 11 -5
C = 6
D + 4 = 14
D + 4 -4 = 14 -4
D = 10
