Abraham, this is the solution of the polynomials division:
5x^3 - 3x^2 + 2x - 1/ x+1
Step 1:
5x² + (-8x² + 2x - 1)/(x + 1)
Step 2:
5x² - 8x + (10x - 1)/(x + 1)
Step 3:
5x² -8x + 10 + (-11/x + 1)
The four numbers below the line are: 5 -8 10 - 11

Your question implies there are choices given with possible answers. As I do not have those in front of me, I will show you how to simplify the radical. It is likely that the answer you seek is the simplified radical.
To simplify
we use the following identity: for positive values of a and b,
That identity allows us to re-write what we are given as
. Let us now consider each of these separately.
Though 50 is not a perfect square it can be written as 25 x 2 and 25 is a perfect square. Thus, we obtain
Next we consider
which is a perfect square as it is equal to
. Thus,
Lastly, we consider
which can be written as
and since
is a perfect square we obtain the following:
Putting that all together we obtain
Answer:
Cost of dryer is $250
Cost of washer is $500
Step-by-step explanation:
Let the cost of the dryer be - x
Then, cost of washer = 2x
To find x,
x+2x= $750
3x=$750
x=$750/3
x=$250
Hope this helps you mate.
