Answer:
(x^2+11)(x^2-11)
Step-by-step explanation:
You didn't list the options, but it should be:
(x^2 + 11) (x^2 - 11)
We use this formula: a^2 - b^2 = (a + b) (a - b)
The answer is 0.25t+30m-59.50
Just combine like terms: (f+g)(x)=x^2+6x+30
Here, we have to analyse the words and ages
The first statement is "Tom is younger than Andy" means Andy is older than Tom. So first comes Andy and then Tom. Let's Rank Andy =1 and Tom = 2 with 1 assigned to the older.
Now, the next statement is "John is not older than Tom" This means John is younger than Tom. This also means Tom is older than John. So John would become the youngest and hence we assign John = 3 (meaning the youngest)
Ordering from Youngest to oldest would be John (Rank 3), Tom (Rank 2) and Andy (Rank 1)
To conclude the order from youngest to oldest would be John,Tom,Andy
<u>Answer:</u>
1 , 
(Answer)
<u>Step-by-step explanation:</u>
Since, 8 chips are selected at random and 5 are there defectives in the lot, So, at least (8 - 5) = 3 chosen chips will be non - defective.
So, P ( At least two of selected part is non defective ) = 1 .
P(first and second samples are defective)
= 
P ( first, second and third samples are defective)
= 
So,
=
=
