Answer:
What grade is this?
Step-by-step explanation:
X = 3
6x + 4 = 22
6x = 18 (subtract 4 from both sides)
x = 3 (divide 6 from both sides)
(x + 2)(x + 2)(x + 2)
(x^2 + 4x + 4)(x + 2)
x^3 + 4x^2 + 4x + 2x^2 + 8x + 8
Simplify
Solution: x^3 + 6x^2 + 12x + 8
The answer is A
I think it is C but it also could be B as well
18 girls and 12 boys 18+12= 30
Brake it up into 15
