a. two column proof

Step-by-step explanation:

This is a two column proof, for 2 columns are given to you.

One column is the "Statements" column, which lists everything in mathematical terms.

The other column is the "Reasons" column, which lists everything by definition (either Theorem, Postulate, or Definition).

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

in if you ask questions, the points are taken from your total and given to the one who answered it..

so if i have 30 points and i ask a question for 5 points, then when someone asks a question i will lose 5 points and the answerer earns 5
