Answer:
4
Step-by-step explanation:
If you graphed it out you would see that the rise/run would be 4 over 1 which is also 4. On this table, you can see that the x is going up by 2 and the y is going up by 8 and 8/2 is also the same as 4/1 or 4 (rise/run = y/x).
So at this point it says “times” so your multiplying and it’s 3 times so you would
do 3x15 and there you have your answer
Answer:
12x⁴ - 15x³ + 18x²
Step-by-step explanation:
1. distribute -3x²
-3x² • 5x = -15x³
-3x² • -4x² = 12x⁴
-3x² • -6 = 18x²
2. combine terms and put in descending order (standard form)
12x⁴ - 15x³ + 18x²
Answer:
31.6%
Step-by-step explanation:
Let the percentage in % be p, then we can solve:
38 * p / 100 = 12
p/100 = 12/38
p = 1200/38 ≈ 31.6%
