How do you solve this?

so for one, just put a line horizontal to line 1

part two I'm assuming you do the same as p since it's not asking you to make it perpendicular to line 1.

part three, create going through line 1 (vertical)

part four constructs the same triangle, but just move the points a little so that way it's not overlapping.

Step-by-step explanation:

parallel means not touching

perpendicular means crossing each other paths.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
