Answer:
M=2
Step-by-step explanation:
This means that 2n is equal to or greater than -1 +10 or -1-10, which can be shown as 2n ≥ 9 and 2n ≥-11, and since 2n ≥11 encompasses both, we can therefore say 2n ≥-11 or n ≥ -5.5 by dividing both sides by 2
Answer:
3. - 8n² -8n + 3
Step-by-step explanation:
(4n^4 - 8n +4) - (8n² + 4n^4 +1)
Firstly, open the brackets.
= 4n^4 - 8n +4 - 8n² - 4n^4 - 1
Now, group like terms.
= 4n^4 - 4n^4 - 8n² -8n - 1 + 4
4n^4 - 4n^4 cancel out with each other since one is negative and the other is positive. So we're left with - 8n² -8n - 1 + 4
= - 8n² -8n - 1 + 4
= - 8n² -8n + 3
