16r^4t-6r^3t^2+4rt^2=

DochEvi [55]

Answer:

$2rt(8r^3-3r^2t+2t)$

Step-by-step explanation:

We have been given a polynomial $16r^4t-6r^3t^2+4rt^2$ and we are supposed to simplify our polynomial.

We will use factoring to simplify our polynomial. Let us factor out the greatest common factor of all the terms.

We can see that 16, 6 and 4 has 2 as their greatest common factor.

The greatest common factor of $r^4, r^3,r$ is r.

The greatest common factor of $t, t^2, t^2$ is t.

So the greatest common factor of the terms of our expression will be $2rt$ .

Let us factor out $2rt$ from our given polynomial.

$2rt(8r^3-3r^2t+2t)$

As we can not factor our expression more, therefore, we will get $2rt(8r^3-3r^2t+2t)$ after simplifying our polynomial.

katie has read 32% of a book. if she has read 80 pages, how many more pages does katie have left to read

Anna35 [415]

X=total number of pages.
1)we calculate the total number of pages.
32% of x =80
(32/100)x=80
x=(80*100)/32
x=250.

2) we calculate the number of pages don´t read.
number of pages don´t read=250-80=170

Answer: 170 pages.
