Answer:
u cannot factor it not possible
Step-by-step explanation:
Each friend would have taken a total of 35 rides each.
This can be verified by multiplying 35 by 35 to get 1225.
8x^2+xy-15y^2
If you need to show work I can put it in the comments :)
Step-by-step explanation:
16⁴ - 2¹³ - 4⁵
= 2¹⁶ - 2¹³ - 2¹⁰
= 2¹⁰(2⁶ - 2³ - 1)
= 2¹⁰(64 - 8 - 1)
= 2¹⁰ * 55
= 2¹⁰ * 5 * 11.
Since it contains 11 in its prime factorization, it is divisible by 11. (Proven)
There are 
ways of drawing a 4-card hand, where
is the so-called binomial coefficient.
There are 13 different card values, of which we want the hand to represent 4 values, so there are 
ways of meeting this requirement.
For each card value, there are 4 choices of suit, of which we only pick 1, so there are 
ways of picking a card of any given value. We draw 4 cards from the deck, so there are 
possible hands in which each card has a different value.
Then there are 
total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is
