The area of a triangle is calculated by the expression given as:
Area = bh/2
where b is the base and h is the height.
We calculate as follows:
270 = b (15) / 2
b = 36
<span>hypotenuse = sqrt ( 15^2 + 36^2 ) = 39</span>
It's 130, any quadrilateral's angles add up to 360 and those numbers add up to 230, 360-230 = 130
An equivalent expression could just be one that is simplified. So we get 9y - 2y - 10 if we distribute the 1/2, which is 7y - 10.

Hope this helps!

I can't figure out a factor for this but graphing it shows x = -2 and +1 as real roots.
