Answer:
Positive 3
Step-by-step explanation:
- * (-3) = 3
The point will be on positive 3, which is above sea level, so it will be above zero.
Expanding (2x² + y²)⁴ with Pascal triangle or using binomial theorem gives:
(2x² + y²)⁴ = 16x⁸ + 32x⁶y² + 24x⁴y⁴ + 8x²y⁶ + y⁸
1) subtract the accepted value from the experimental value.
2) Take the absolute value ofvstep 1
3) Divide the answer by accepted value
4) Maltiply that answer by 100 and add the % symbol to express the answer as a percentage.
BC = 8i + 6
This is the answer for the first question, i'm so so sorry but i'm not sure what the answer is to the second one.
