Step-by-step explanation:
using a SNC
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.

√1² + -7² = d
d = 7.1
Answer:
n = 2
Step-by-step explanation:
In order for the ratio to have a value of 1, the sum of exponents in the numerator must equal the sum of exponents in the denominator:
n + 7 = 9
n = 9 -7 . . . . . . subtract 7 from both sides of the equation
n = 2
___
Alternatively, you can simplify the given expression:

Hopefully, it is clear to you that the value of n must be 2 in order to make the numerator equal to the denominator.
C) 18 because you could get 6 numbers with red, 6 numbers with brown and 6 numbers with yellow.
