What is the result when 9r^3 + 27x^2 + 11x +1 is divided by 3x + 1?​
morpeh [17]

Answer:

the answer is 3x^2 + 8x + 1

Step-by-step explanation:

(I used x as the variable due to the invalid difference of variables in your question )

To find the correct answer, I had to use polynomial division.

(9 x 3 + 27 x 2 + 11 x + 1) / (3 x + 1)

= ( 3 x + 1 ) ( 3 x 2 + 8 x + 1 ) / (3 x + 1)

= 3 x 2 + 8 x + 1

PLS SOLVE ASAP!!!

The new line intercepts the y axis at point (0, 1), so that is the end of the equation, and I believe the slope of the line is 1 because each corner of each square on the grid is connected. This gives you the equation of y = 1x + 1, or        y = x + 1. I hope this helps!
