3x + 8 = 3x + []
Subtract 3x from both sides.
[] = 8
If you want no values of x, it can be any positive value other than 8.
If you want all values of x, the value must be 8.
If you want only one value of x, it is impossible because both equations have the same slope.
Intersecting lines are lines that meet at some point while perpendicular lines are intersecting lines that makes a right angle at the point of intersection.
Two line can either be intersecting or perpendicular. It is not possible to have two line that is neither intersecting or parallel.
Answer:
Length: 6 ft
Width: 4 feet
Step-by-step explanation:
Length: L
Width: 2L - 8
2L + 2(2L - 8) = 20
2L + 4L - 16 = 20
6L = 36
L = 36/6
L = 6
W= 2(6)-8 = 4
