Answer:
16
Step-by-step explanation:
The constant is the term without any variables (like letters x or y) attached to it.
Looking at the equation, we see that -14x, 6x, and 2y are all terms with a variable. Only 16 is solely a number.
Thus, the answer is 16.
Step-by-step explanation:
5 because you have to round
3x + 4
2x + 5|6x² + 23x + 20
6x² + 15x
8x + 20
8x + 20
0
The answer is B.
(2n³ + 4n² - 7) + (-n³ - 8n - 2)
(2n³ - n³) + 4n² - 8n - 7 - 2
n³ + 4n² - 8n - 9
The answer is B.
2x² - 10x - 12
2(x²) - 2(5x) - 2(6)
2(x² - 5x - 6)
2(x² - 3x - 2x - 6)
2(x(x) - x(3) - 2(x) - 2(3))
2(x(x - 3) - 2(x - 3))
2(x - 2)(x - 3)
The answer is A.
4ab - 8a² + 12ac = 4ab - 8a² + 12ac = b - 2a + 3c
4a 4a 4a 4a
The answer is B.
