Step-by-step explanation:
<span> irrational number is </span>√2
answer is A. √2
Answer:
The answer is A. (or the first one)
Step-by-step explanation:
It's not D because the median is 46. It is not B or C either because the IQR is 35 and the OQR is 53.5 and A is the only one that has that. Hope it helped :)
Answer:
Step-by-step explanation:
What we want to fator is:
There is no common factor, but let's factor it by grouping. The first two addends can be factor as follows:
the second addends can be factor as well:
.
Then our original expression can be rewritten like
And here the is the common factor!
Finally, we can factor the quadratic expression as a difference of squares
Ant we get
now, we can extract the negative sign from , and we get
.
Answer:
24x²y²
Step-by-step explanation:
For k=0 to n, the k-th term of (a+b)^n is ...
(nCk)·a^(n-k)·b^k
You want the k=2 term for the n=4 expansion with a=2x and b=-y.
Then the third term of the expansion is ...
(4C2)·(2x)^2·(-y)^2 = 6·4x^2·y^2 = 24x^2y^2
_____
nCk = n!/(k!(n-k)!)
4C2 = 4!/(2!·2!) = (4·3)/(2·1) = 6
