Answer:
y=0
Step-by-step explanation:
8=8
<h3>
===> Exercise 1</h3>
(3x² - 7x + 14) + (5x² + 4x - 6)
Match 3x² and 5x² to get 8x².
Combine −7x and 4x to get −3x.
Subtract 6 from 14 to get 8.
Therefore, the expression (3x² - 7x + 14) + (5x² + 4x - 6), is equivalent to the expression "B".
<h3>
===> Exercise 2</h3>
(2x² - 5x -3) + (-10x² + 2x + 7)
Combine 2x² and -10x² to get −8x².
Combine −5x and 2x to get −3x.
Add −3 and 7 to get 4.
Therefore, the expression (2x² - 5x -3) + (-10x² + 2x + 7), is equivalent to the expression "A".
<h3>
===> Exercise 3</h3>
(12x² - 2x - 13) + (-4x² + 5x +9)
Combine 12x² and -4x² to get 8x².
Combine −2x and 5x to get 3x.
Add −13 and 9 to get −4.
Therefore, the expression (12x² - 2x - 13) + (-4x² + 5x +9), is equivalent to the expression "C".
