-2xy+3x-2xy+3x
-2xy-2xy+3x+3x ( combine like terms)
-2xy-2xy=-4xy
3x+3x=6x
-4xy+6x
Answer: B. -4xy+6x
Two or more points are said to be collinear if they lie on the same straight line.
Given a straight line XY, with a point P on the straight line between point X and Y, then
XP + PY = XY
From the question, it was given that AB = 7 and BC = 4, so if A, B, C are colinear, then
AB + BC = AC
i.e. 7 + 4 = 11
But, from the equation, AC = 9.
Therefore, points A, B and C are not collinear.
Answer: The exact distance is
units
The approximate distance is roughly 8.5440037 units
===========================================================
Explanation:
Use the distance formula

As an alternative, you can use the pythagorean theorem.
Its the second one yeah im pretty sure
FSJ is similar to DYJ
DY || FS
42/63 = 50/x
2/3 = 50/x
x = 75
