Answer:
8t^3-36t^2+54t-27
Step-by-step explanation:
(2t-3)^3
(2t-3)(2t-3)(2t-3)
Multiply the first two terms
(4t^2 -6t -6t+9)(2t-3)
Combine like terms
( 4t^2 -12t +9) ( 2t-3)
Multiply
2t*( 4t^2 -12t +9) -3 ( 4t^2 -12t +9)
Distribute
8t^3 -24t^2 +18t-12t^2 +36t-27
Combine like terms
8t^3-36t^2+54t-27
Answer:
There would be 350 girls in the school.
Step-by-step explanation:
We can find this by creating two proportions. the first fraction would be the number of girls out in the sample:
7/12
The second part would be the amount of girls in the whole school. We can set the girls as x since we do not know.
x/600
Now we can set the two equal to each other and cross multiply.
7/12 = x/600
600*7 = 12*x
4200 = 12x
350 = x
I don't think anyone can read that, sorry!
