Solve the following equation algebraically 3x^2=375

d. x= +-11.18

Step-by-step explanation:

X = approximately 11.2

Step-by-step explanation:

3x^2 = 375

3x^2/3 = 375/3

x^2 = 125

√x^2 = √125

x= approximately 11.2

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.
