First,we would list out the possibilities to find the probability:
Let G represent girl and B represent boy,here are the possibilities:
1)GGGGGG
2)GBBBBB
3)GGBBBB
4)GGGBBB
5)GGGGBB
6)GGGGGB
7)BBBBBB
Since there are 7 probabilities,the probability is 1/7.
Hope it helps!
Answer:
B and D
Step-by-step explanation:
(2x-6):(6x-4)
you can divide everything by 2
2x÷2=x, -6÷2=-3
6x÷2=3x, -4÷2=-2
so it's B X-3:3x-2
(2x-6):(6x-4)
multiply everything by 2
2x × 2 = 2x, -6 × 2 = -12
6x × 2 = 12x, -4 × 2 = -8
so it's D (4x-12): (12x-8)
Answer: B
(2x + 6)^2 can be rewrote as (2x + 6)(2x + 6).
Multiply out to get 4x^2 + 24x + 36
D because 5.50 is x and your y so boom D
