Answer:
2x² + 6x - 4
Step-by-step explanation:
f(x) - g(x)
= 3x² + x - 3 - (x² - 5x + 1) ← distribute
= 3x² + x - 3 - x² + 5x - 1 ← collect like terms
= 2x² + 6x - 4
Answer:
18^5
Step-by-step explanation:
18^9 ÷ 18^4
= 18 ^ (9-4)
= 18 ^ 5
The answer is the last one. This is because negatives don't work in a square root.
Answer:
15
Step-by-step explanation:
To answer this, we would have to look at the last place first, which is the hundredths place. In the hundredths place, we have a 2. 2 is less than 5, so we would just pretend it isn't there since we would round down. Now, looking at the tenths place, which is the 6, we can determine whether or not we round. If the number is 5 and above, (including 5) we would round up. In this case, it is 6, so we would round the number in front of it (4) up by one to get 15.
