Question

Find the sum of 8, x, minus, 28x - 2, and minus, 3, x, squared, minus, 7 - 3x^2 - 7.

a) 6x - 1
b) 4 - 2x
c) -2x - 2
d) -3x^2 + 6x - 2

Answer 1

The sum of 8, x, -28x - 2, and -3x^2 - 7 - 3x^2 - 7 is -6x^2 - 27x - 8, which does not match any of the provided answer choices, indicating a possible error in the problem's transcription or the answer choices.

Step-by-step explanation:

The student is asking to find the sum of 8, x, -28x - 2, and -3x2 - 7 - 3x2 - 7. When we combine like terms, we have:

• 8, which is a constant,
• x - 28x, which combines to -27x (since x - 28x = -27x),
• -3x2 - 3x2, which combines to -6x2 (since -3x2 - 3x2 = -6x2), and
• -2 - 7 -7, which combines to -16 (since -2 - 7 - 7 = -16).

Therefore, the sum is -6x2 - 27x + 8 - 16, which simplifies to -6x2 - 27x - 8.
