(2x-5y) + (x+y)
= (2x+x) + (-5y+y)
= 3x + (-4y)
= 3x-4y
So option A is the correct one.
First let's rewrite it...
18a^2 + 20a + 8
Factor out a 2
2 (9a^2 + 10a + 4)
Circumference = square root (Area * 4 * PI)
circumference = square root (

</span>
</span>
* 4 * PI )
<span>circumference = square root (
5,684.8921350275)
</span>circumference =
