Answer: A
Step-by-step explanation: As it is a data set that has been equally represented, it is ok to predict.
Each year is 12 months so it would be 1.5 years
Your answer would be 8n³ + 6n² - 4n - 20.
The horizontal method for simplifying binomials is to simply multiply the terms in the first bracket by the terms in the second bracket. Written out, this looks like:
(2n² × 4n) + (4n × 4n) + (4 × 4n) + (2n² × -5) + (4n × -5) + (4 × -5).
Then, we just need to do the operations in the brackets, which gives us:
8n³ + 16n² + 16n - 10n² - 20n - 20
And finally we collect the like terms to simplify, which means doing 16n² - 10n² = 6n², and 16n - 20n = -4n, so the final answer is 8n³ + 6n² - 4n - 20.
I hope this helps!
Responder:
3 * 10²
4 * 10³
5 * 10⁴
7 * 10 ^ 5
Explicação passo a passo:
Expressando o seguinte como um produto de um número natural e uma potência base de 10.
Lembrar :
10 = 10¹
100 = 10 * 10 = 10²
1000 = 10 * 10 * 10 = 10³
Portanto,
300 = 3 * 100 = 3 * (10 * 10) = 3 * 10²
4000 = 4 * 1000 = 4 * (10 * 10 * 10) = 4 * 10³
50000 = 5 * 10000 = 5 * (10 * 10 * 10 * 10) = 5 * 10⁴
700000 = 7 * 100000 = 7 * (10 * 10 * 10 * 10 * 10) = 7 * 10 ^ 5
