What is the sum of the polynomials? (–x2 + 9) + (–3x2 – 11x + 4) –4x2 – 2x + 4 –4x2 – 11x + 13 2x2 + 20x + 4 2x2 + 11x + 5

The sum of the given polynomials is:

We are asked to simplify the given algebraic expression i.e. we have to sum two polynomials which are given in terms of variable x:

      We have to simplify:

On combining the like terms that is the terms with same power of x are kept together as:

     Hence, the correct simplification of the given variable is:

Step-by-step explanation:

To find the sum of  

First we open parenthesis , we get

   [∵  (-)(+)=(-)]

Now, combine the like terms , we get

Simplify ,

Therefore , the sum of the polynomials is

step-by-step explanation:

first you will have to convert 3/4 into a decimal

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

answer: i think one of the answer is $150 and $300?
