1 answer:
Second number - n
First number- <span>5 times of another number - 5n
Adding 8 to each number:
n+8
5n + 8
</span><span>First number becomes 3 times the second number:</span><span>
5n + 8 = 3(n + 8)
5n + 8 = 3n + 24
2n = 16
n = 8 is a second number
5n = 5*8 = 40 is a first number
Numbers are 40 and 8.

Answer:
x = 2√13.
Step-by-step explanation:
Using the Pythagoras theorem:
14^2 = x^2 + 12^2
x^2 = 14^2 - 12^2
x^2 = (14 + 12)(14 - 12) = 52
x = √52
x = √4*√13
x = 2√13.
Answer:
yes
Step-by-step explanation:
you can tell because all of the x-values are different, or they dont repeat. a function is no repeating x-values.
