$=\tt x - 3 + 7(x + 3) - 3x - 12$

$=\tt x - 3 + 7x + 21 - 3x - 12$

$=\tt 7x + x - 3x - 3 - 12 + 21$

$=\tt 8x - 3x - 15 + 21$

$\color{plum}=\tt\bold{ 5x + 6}$

<h3>▪︎Therefore :</h3>

$\color{hotpink} =\tt x - 3 + 7(x + 3) - 3x - 12 \color{plum}=\tt\bold{ 5x + 6}$

Tamiku [17]

Answer:

The correct option is b.

Step-by-step explanation:

The formula for standard deviation is

$\sigma^2=\frac{\sum {(x-\overline{x})^2}}{n}$

where, $\overline{x}$ is mean of the data and n is number of observation.

The variance of a stock's returns can be calculated by the above formula.

Variance of stock's returns is the average value of squared deviations from the mean.

Therefore the correct option is b.

Simplify.

Citrus2011 [14]

First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!
