Answer:
5a + (-6a) + (-2b) + 2b + (-3) = -a -3 or -(a + 3) so first answer is correct because -(a + 3) is the same as -(3 + a)

It has to be 5 because 2.5 is half so the other half 2.5 .so 2.5 +2.5 =5
In a rhombus, the diagonals meet at right-angles, and they bisect each other, namely they cut each other in half, check the picture below.
thus we can use the pythagorean theorem to get one side, keeping in mind that, slanted as it may be, all sides in a rhombus are equal in length.
We can have two or more points lying on the same line collinear.
So we can say points lying on same line are collinear but a line cannot be collinear.
