Answer:
(x+5)²-10x²
Step-by-step explanation:
USing the completing square method
x² +25
= (x)² +2(x)(5) +(5)² -10x²
=(x+5)²-10x²
No not always, because x could be a smaller number than y which would make it an negative. If x is bigger than y most likely it will be, but not always.
Answer:
<h2>4/11</h2>
Step-by-step explanation:
Probability is the likelihood or chance that an event will occur.
<em>Probability = expected number of outcome/Total number of outcome</em>
If there are group of 11 people, then the total outcome of events will be 11
If we are to select 4 oldest people from the group, then the expected outcome is 4.
Hence, the probability that the 4 oldest people in the group were selected is 4/11.
