That is distributive property ... hope this helps
The correct question is; x² + 2x - 24
The other factor of <em>x² </em><em>+</em><em> </em><em>2x </em><em>-</em><em> 24</em> asides (x+6) is; (x-4)
The expression given can be factorised as follows;
Consequently, the other factor of the expression is (x-4).

Notice how the top is an addition of two cubes, namely x and 2.
You can rewrite the equation as:

Now, (a + b)³ can be simplified down to (a + b)(a² - ab + b²)
Following the same pattern, we get:

<span><span>1. </span>Simply divide the 520 to 36 and that makes it 15</span>
SU would be the hypotenuse so you can use Pythagorean Theorem to solve this problem.
42^2 + 56^2 = c^2
1764 + 3136 = c^2
4900 = c^2
70 = c
