Which polynomial correctly combines the like terms and puts the given polynomial in standard form? -5x^3y^3+8x^4y^2-xy^5-2x^2y^4
victus00 [196]

Given:

The polynomial is:

-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5

To find:

The simplified form of the given polynomial in standard form.

Solution:

We have,

-5x^3y^3+8x^4y^2-xy^5-2x^2y^4+8x^6+3x^2y^4-6xy^5

Combining the like terms, we get

=-5x^3y^3+8x^4y^2+(-2x^2y^4+3x^2y^4)+8x^6+(-xy^5-6xy^5)

=-5x^3y^3+8x^4y^2+x^2y^4+8x^6-7xy^5

Now, rewrite this polynomial in standard form.

=8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5

Therefore, the required polynomial in standard form is 8x^6+8x^4y^2-5x^3y^3+x^2y^4-7xy^5.

By direct division, we will find that the length of each piece of rope is 10.5m

<h3>How to perform the division?</h3>

So e start with a 42 meter long rope and we cut it into 4 equal parts, then we know that each one of these pieces will have a length equal to:

L = (42m/4)

To perform that division, you can see that 42<u> is not a multiple of 4</u>, so we can write:

L = (40m + 2m)/4 = (40m/4) + (2m/4)

The first quotient is just equal to 10m, while the second one is:

(2m/4) = (1m/2) = 0.5m

Then we have:

L =  (40m/4) + (2m/4) = 10m + 0.5m = 10.5m

Each piece of rope has a length of 10.5m
