Answer: 
Step-by-step explanation:
You need to remember the Distributive property:

And the multiplication of signs:

Therefore, applying the explained before, to simplify the expression
you need to multiply each term that are inside of the parentheses by -2, then you get:

We have that
<span>line with endpoints at (1,3) and (3,1)
we know that
Applying </span><span>the distance formula
d= √ (x2-x1)^2+(y2-y1)^2
</span>d= √ (3-1)^2+(1-3)^2-------> d=√[2²+(-2)²]-----> d=√8
Answer:
20
Step-by-step explanation:
We know that the formula for the area of something is 1/2 * base * height
So we multiply 1/2 * 8 * 2 for The first triangle and get 8
Repeat for the other 3:
1/2* 2*2 = 2
8+8+2+2 = 20
* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.
I hope this helps :)
