Answer:
Step-by-step explanation:
commutative property of addition : x + y = y + x
example : 2+3 =5 and 3+2 =5 then 2+3=3+2
associative property of addition
x + y + z = (x + y) + z = x + (y + z)
example: 2+3+4 = (2+3)+4 = 5 + 4 =9
2+3+4 = 2+(3+4) = 2 + 7 = 9
Answer: x1 = 5
x2 = 1
1. Identify the coefficients
2. Move the constant to the right side of the equation and combine
3. Complete the square
4. Solve for x
I think it would be 2+ -11
2:3
2 would represent the Fraction of girls 3 would represent the fraction of boys.
