What is the expanded form of 3x(x+3)^2?

1 answer:

7 0

We need to expand the square binomial and then multiply:
3x(x + 3)^2
= 3x(x + 3)(x + 3)
= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x

Answer:

$n = -5$

Step-by-step explanation:

Given

$Digit = 0.000025$

Required

Rewrite using scientific notation, then find n

$Digit = 0.000025$

Express as fraction

$Digit =\frac{25}{1000000}$

This can be splitted to

$Digit = 25 * 10^{-6}$

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

$Digit = 2.5 * 10* 10^{-6}$

Apply law of indices

$Digit = 2.5 * 10^{1-6}$

$Digit = 2.5 * 10^{-5}$

Comparing n, the given options

$n = -5$
