Let's work out the discriminant b^2 - 4ac:-
D = (-5)^2 - 4*1*7 = 25 - 28 = -3
A negative discriminant shows that there are NO real solutions Answer
Answer:
There would be 94 tiles.
Step-by-step explanation:
The number of tiles is given by the following equation:

In which p is the current position.
How many tiles would there be in position 22?
This is n when
. So

Answer:
10
Step-by-step explanation:
Because 6+4 is 10. When u do these look at the number u know and add them together to get the first number
√-25
= √(25*-1) = √25 * √-1 = 5i, where i = √-1
The principal square root = 5i
