so it means
a21 = 231
Answer: c
Step-by-step explanation:
Answer:
1. Slope = -2
2. Slope = ⁴/3
3. Slope = -3
4. Slope = 1
Step-by-step explanation:
1. Using two points on the line, (0, 0) and (-1, 2):

2. Using two points on the line, (0, 0) and (3, 4):

3. Using two points on the line, (0, 0) and (-1, 3):

4. Using two points on the line, (0, 0) and (2, 2):

21x³ - 18x²y + 24xy²
Simplify!
7x³ - 6x²y + 8xy²
The answer is 560. So I hope this helps you.
