-12 because 3x4=12 so you lose 12 points is -12
Answer:
No, it is <em>not</em> a right triangle.
Step-by-step explanation:
We know that there are <em>2 legs </em>and <em>1 hypotenuse</em>. The <em>hypotenuse is 76</em> because it is the<em> largest number</em>. And the two <em>legs are 73 and 26</em>. Now to find if it is a right triangle we will take <em>73 and multiply it by itself</em>, which is <em>5,329</em>. Now we will do the same with 26 and we get <em>676.</em> Then we <em>add 676 to 5,329</em> and we get <em>6,005</em>. Because we are trying to find the hypotenuse, we have to find what number <em>when squared</em> makes<em> 6,005</em>. Since <em>76 x 76 = 5,776</em> it is<em> not a right triangle. </em>
Here is an image of the triangle:
Answer:

Step-by-step explanation:
The polynomial given is: 
<em><u>Grouping the first 2 terms together and the last 2 terms together and taking common, we have:</u></em>

This is the complete factorization.
90 because 84 plus 90 divided by 2 is 87.
I'm not sure if that's the correct method of finding that (it could be, I was just never shown that kind of method). What I did was multiply everything out, that way you have two numbers vs two equations. Then add those two numbers and turn that into scientific notation.
