For this case, the first thing we should do is use the following equation:
x ^ 2 + x-30
Here, we substitute the value of x = 20
We have then:
(20) ^ 2 + (20) -30 = 390 m ^ 2
Answer:
the area of the land when the length of the dentist's office is 20 meters is:
390 m ^ 2
We know that there are 36 number cards and 16 face cards in standard deck of 52 cards. Now choose two cards without replacement from 52 cards.
The number of ways of choosing any 2 cards without replacement from 52 cards is
.
The number of ways of choosing 2 number cards without replacement from 36 cards is
.
The required probability is

Correct choice is (A).
The answer is 8.75 because 7 * 5 is 35 / 4 = 8.75
