A. m/5
That is the answer because there are 5 of you, and the money is divided between 5 people.
Notice that half of the coefficient of x is (1/2)(-4), or -2.
Then x^2 - 4x becomes
x^2 - 4x + 4 - 4 = 0, or (x -2)^2 = 4. Then x = -2 plus or minus 2, and the two roots are 0 and -4.
Thus, add 4 to both sides to obtain x^2 - 4x + 4 = 4.
I believe the next one would be 13.2 because if you add 8.4 to -6.4 it gets 4.8 so you just do the same thing
Answer:
1. X/2 = 4
2. 3x - 2 = 11
3. 2x - 5 = 15
4. 2x-1=12
5. 9x = 2(x+5)
