54c^3d^4 + 9c^4d^2
9c^3d^2(6d^2 + c)
84 pounds on earth is about 14 pounds on the moon but to be exact it is 13.89 pounds.
Answer:
step 1. A, B,D are incorrectly written as these are not all coordinates. they must be written (x, y)
step 2. so the question becomes is C a quadratic
step 3. The x values must be evenly spaced. the x values are evenly spaced by a difference of 4
step 4. write out the y values: -126, -14, 2, 18
step 5. write out the differences: 140, 16, 16
step 6. write out the differences: -124, 0.
step 7. after doing this twice the numbers nust be the same for this to be a quadratic which they aren't
step 8. C is not a quadratic.
