Answer:

3x(3x³ + 8x² – 9x + 4)

Step-by-step explanation:

9x4 + 24x3 - 27x2 + 12x =

9x⁴ + 24x³ – 27x² + 12x =

3(3x⁴ + 24x³ – 27x² + 12x) =

3x(3x³ + 24x² – 27x + 12).

3x³ + 24x² – 27x + 12 cannot be factored

Which number is greatest? 2.89 times 10 Superscript negative 8 1.997 times 10 Superscript 2 8.9 times 10 Superscript negative 6

love history [14]

<h3> The greatest number is $1.997 \times 10^2$ </h3>

<em><u>Solution:</u></em>

<em><u>Given that the numbers are:</u></em>

$2.89 \times 10^{-8}\\\\1.997 \times 10^2\\\\8.9 \times 10^{-6}\\\\5 \times 10^{-6}$

We have to find the number that is greatest

Convert the numbers to decimal

$2.89 \times 10^{-8} = 2.89 \times \frac{1}{10^8} =0.0000000289$

$1.997 \times 10^2 = 199.7$

$8.9\times 10^{-6}=8.9\times \frac{1}{10^6}=0.0000089$

$5\times 10^{-6}=5\times \frac{1}{10^6}=0.000005$

We can clearly see that, 199.7 is greatest number

Thus the greatest number is $1.997 \times 10^2$

P = 4s where s is the side length

100 =4s

Divide each side by 4

100/4 = 4s/4

25 = s

A = s^2 for a square

A = 25^2

A =625

Answer:

Step-by-step explanation:

the mean is calculated as

mean = $\frac{sum}{count}$

this year's mean = $\frac{7+3.3+2}{3}$ = $\frac{12.3}{3}$ = 4.1

last year's mean = $\frac{5.3+1.6+2.4}{3}$ = $\frac{9.3}{3}$ = 3.1

difference = 4.1 - 3.1 = 1
