Here, the probability of the first card drawn is a king is same as before i.e. 113
1
13
. Now, this card is not returned to the deck. So, the number of cards in the deck becomes 51 and the number of kings is also one less i.e. 3. So, the probability of the second card drawn is a king is 351=117
3
51
=
1
17
. Hence, the required probability is 113∗117=1221

A rectangle has a height of k^2+3k 2 +3k, squared, plus, 3 and a width of k^2+7k 2 +7k, squared, plus, 7. Express the area of th
vlada-n [284]

Answer: k^4+10k^3+21k^2

Step-by-step explanation:

Given

Height of rectangle is h=k^2+3k

Width is w=k^2+7k

The area of the rectangle is given by the multiplication of the height and width

\Rightarrow A=\left(k^2+3k\right)\left(k^2+7k\right)\\\\\Rightarrow A=k^2k^2+k^2\cdot \:7k+3kk^2+3k\cdot \:7k\\\\\Rightarrow A=k^4+10k^3+21k^2

Thus, the area of the rectangle is k^4+10k^3+21k^2.
