We have to name a line that "contains" point P. This means that we have to find a line that passes through point P. We can see that line PS/n goes through point P.

We have to find the plane's name. The name (usually a letter) is usually on a corner of the plane, in caps. We could see that there is an F on the bottom left hand corner of the plane, so F is our plane name.

To name an intersection of lines n and m, we have to find the point where they intersect and name it. We could see that point R goes through both lines, so that is our answer.

We have to name a point that does not contain lines l, m, or n. Point W is a point that is not on any of the lines.

Another name for line n is also line PS (add a line on the top of PS when writing this!) because point P and point S are two points on line n.

Line l does not intersect lines n or m because those lines do not go through line l at all.

10 (x/2 +6)=8
10x/2 +60=8
Subtract 60 from both sides
10x/2+60-60=8-60
10x/2= -52
Multiply both sides by 2
(10x/2)*2= -52*2
10x= -104
Divide both sides by 10
10x/10=-104/10
Answer: x= -10.4
First identify the a, b, c of the quadratic:
A= -2, B= 0, and C= 3
There’s no b value since there’s no x term, just a constant and an x^2
The square root of (0)^2-4(-2)(3) is equal to 24
