Help Pl 15 Points to the fastest 5. Adam simplified the expression below incorrectly.

4(x – 5) + (3x + 15) – 5x
4x – 5 + 3x + 15 – 5x
4x + 3x – 5x – 5 + 15
(4x + 3x – 5x) – (5 + 15)
2x – 20

Review Adam’s work and write a note explaining to him how to correct his mistakes.

Show the correct steps in simplifying the expression.

He did not multiple the initial 5 by 4 when he multiple the x by 4

Step-by-step explanation:

what? that isnt a question

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
