Answer:
the empty set {∅}
Step-by-step explanation:
{x | x < -3} ∩ {x | x > 5} is giving us
(-∞, -3) intersecting (5, ∞).
Since those two intervals do not intersect the solution is the empty set
The length of one side is 17 meters because 68÷4=17. The 68 is 68 meters and 4 is how many sides a square has.
Given the following question:
Point A = (7, 4) = (x1, y1)
Point B = (3, 6) = (x2, y2)
To find the slope use rise over run:

m = -0.5
1/7-9/7n+6/7
1-9/7n
that is the extended form and is simplified
