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.

1/4 and 8/3 because:

the reciprocal if 4 is 1/4 because 4 is used as 4/1 and the opposite of that is 1/4. the opposite of 3/8 is 8/3 so that is the answer.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap
