Answer:
Step-by-step explanation:
1). If a point C is lying on a line segment RB,
Then RB = RC + CB
Since, RB = 45, CB = 3x - 12 and RC = 2x + 9
45 = (2x + 9) + (3x - 12)
45 = (2x + 3x) - 3
48 = 5x
x = 
x = 9.6
2). Since, RC = 2x + 9
RC = 2(9.6) + 9
= 19.2 + 9
= 28.2 units
3). Distance between the two points 
and 
is given by the formula,
d = 
Distance between the points A(2, -2) and D(-2, 2) will be,
= 
= 
= 5.657
≈ 5.66 units

Answer:
I didnt know but i worked it out and searched it up and i got this
Step-by-step explanation:
(2a+4c-5b+2a+5b-4c)
The length of the rectangle is n-3, ok, the width is 2
the area of a rectangle is just length * width
so, if you simplify either of those, you'd end up with 2n-6.
because same/same = 1, and 1 * anything, is just anything itself.
