What are the solution(s) of X2-4=0?

-2 or 2

Step-by-step explanation:

So we have the equation:

Add 4 to both sides:

Take the square root of both sides:

Therefore, our answers are -2 or 2.

And we're done :)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.

the answer is. -82562234434584
