What is the simplelest form of the following expression? 6c^2+2.5d-d+2c^2-3d a) 4c^2-1.5d b)6c^2+0.5d c)8c^2-1.5d d)8c^2+1.5d

The correct option is c.

Step-by-step explanation:

The given expression is

Like terms are those terms which have same variable having same degree.

On combining like terms we get

On simplification we get

The simplest form of given expression is .

Therefore the correct option is c.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
