Answer:
Answer:
(x -6) (x -6) or (x -6)^2
Step-by-step explanation:
Given : x^2 − 12x + 36
since the leading coefficent for this equation is 1, we take 36 and find 2 factors that 36 has, and also adds up to -12. That would be -6, and -6 because -6 + -6 = -12 AND -6 x -6 = 36 , therefore -6 and -6 are the numbers we are looking for. Which makes this the anwer:
(x -6) (x -6) or (x -6)^2

Let the number of boys be x
Let the number of girls be x + 4
(x + 4) + x = 28
x + x + 4 = 28
2x + 4 =28
2x = 28 - 4 → 2x = 24 → x = 24 / 2 → x = 12
The number of boys is 12, so the girls are 12 + 4 = 16
Ratio of girls to boys → 16 : 12 → 4 : 3
Ratio of girls to boys is 4:3
18
81
92
Answer:
The answer is 81 because 9x9=81
