The answers are overall different. But there are similarities. Both equations have an addition sign. Both also have double digit numbers being added together.
The polynomials which, when added to the polynomial 3x²+3x-1, is equivalent to the following expressions: 1, 2x²-3, and x+5 are respectively;
- P = 2 - 3x² -3x.
- P = -2 -x² -3x
- P = 6 -2x -3x².
<h3>Addition of polynomials</h3>
For the expression; 1; we have;
P = 2 - 3x² -3x.
For the expression; 2x²-3; we have;
P = -2 -x² -3x
For the expression; x +5; we have;
P = 6 -2x -3x².

Answer:
option D
2x − 7(−3x − 17) = 4
Step-by-step explanation:
Given in the question two equations
<h3>Equation 1</h3>
2x - 7y = 4
<h3>Equation 2</h3>
3x + y = -17
Rearranging equation 2 in terms of y
3x + y = -17
y = -17 - 3x
Put this value of y in Equation 1
2x - 7y = 4
2x - 7(-17 - 3x) = 4
So,
If you use the substitution method to solve the following system, new equation will be
<h3>2x - 7(- 3x - 17) = 4 </h3>
1 is 4y
2 is y-2+2 im sure sorry if this dont help
