Guest #3, you are incorrect

Two negatives do equal a positive. You will also convert the minus sign into a plus sign so it would end up being 4 + 2.

4 + 2 = 6

-4 - -2 = -2 

You can do a method i use called "Keep Change Change" which only applys when subtracting by a negative. You keep the first number, change the sign, and change the last number. (ex. -4 -  -2 = -4 + 2)

2 negatives equal a positive

-4+2=-2

-2

The pythagoreom theorem is just a formula, used to find the sides of a right triangle

a^2+b^2=c^2

A is one side in a triangle

B is the other side

C is the hypoteneuse, i.e. the side opposite of the 90 degree vertex

plug in each variable, square them, and it should be equal

the formula is A^2 + b^2 = c^2 A & B being the sides, and C being the hypotenuse.

x/18=20

multiply by 18 on each side

20*18 = 360

x=360

What is the answer to this question. Also show your work. A music store sells a used guitar for 120 dollars. This is 25 dollars mor than half the cost of a new guitar of the same brand. What is the cost of a new guitar?

Let the price of a new guitar=G
