The answer is D +14 because to negatives make a positive
Explanation:
The easiest way to do this is to make use of the 2-point form of the equation for a line. For points (x₁, y₁) and (x₂, y₂), the equation is ...

Filling in your given points, the equation becomes ...

After you fill in the values, it is a matter of simplifying the resulting equation.

Answer:
9x+6
Step-by-step explanation:
I think by equivalent, you mean solve it.
5x+(x+6)+3x
5x+x+6+3x, open the parenthesis
9x+6, add up the like terms
<h3><u>Solution:- </u></h3>
Let the number to be added be A
Now,

Transposing (−5x³+ 4x − 3 ) to other side-

Remember if there is a -ve sign before a bracket the signs of whole of the terms changes on opening bracket

Putting like terms together -


Therefore, 5x³+x²-5x +2 should be added to −5x³+ 4x − 3 to get x²− x − 1
