Answer:
There are 2,598,960 ways to receive 5 cards from a deck of 52.
Step-by-step explanation:
The order in which the cards are chosen is not important, which means that the combinations formula is used to solve this question.
Combinations formula:
 is the number of different combinations of x objects from a set of n elements, given by the following formula.

Answer:
The solution of y² - 1 = 15  is +4 and -4
Step-by-step explanation:
Given 
y² - 1 = 15 
Our solution goes thus;
Make y² the subject of formula
y² = 15 + 1
Add 15 to 1
y² = 16
Take square roots of both sides
√y² = √16
y =  √16
Note that the square root of 16 is either +4 or -4 because +4 * +4 = 16 and -4 * -4 = 16; So, we replace √16 with ±4 which means + or -4
y = ±4
y = +4 and -4
Hence, the solution of y² - 1 = 15  is +4 and -4

- SAS
- 1, 2, 3, 4, and 5
- using alternate interior angles theorem on angles A and C, verticle angles theorem on angle O, and the Parallelogram Diagonals Theorem Converse  you can prove triangles ADO and BOC are similar. Then using  CPCTC "Corresponding parts of congruent triangles are congruent" you can prove that line segment AO is congruent (equal) to line segment CO
