Travel distance by light in a second = 3*10^5 kms
Travel distance by light in 60 seconds =
3*10^5 * 60
180 * 10^5
1.8 * 10^7 kms
Answer: The three different equations will be

Step-by-step explanation:
We have to write three equation that have x = 5 as a solution:
1) First equation will be

2) Second equation will be

3) Third equation will be

Hence, the three different equations will be

B. x^2 + 5x - 4 = 0
Anyway that you try to factor it will not work
~~hope this helps~~
it could be 2.2 because every 5 you get 2 so it would be 10 and 4 so when y=6 then x should be 2.2.
