YO PLZ HELP!! MARKING BRAINIEST!!
Yuliya22 [10]

Answer:

x = 26, 16

Step-by-step explanation:

( x-21) ^2 = 25

Take the square root of each side

sqrt(( x-21) ^2) = ±sqrt(25)

x-21 = ±5

Add 21 to each side

x-21+21 = 21±5

x = 21±5

x = 21+5  and x = 21-5

x = 26, 16

Herodoto, historiador
Masja [62]

Answer:

Defining the straight number of integers, we have to live in the year 2020 and this Greek historian was born in the year - 484.

Step-by-step explanation:

When using whole numbers, we denote positive numbers as the number of numbers after 0, and negative numbers the number of numbers before zero.

So if we consider the birth of Christ to be the year 0, then all years before Christ will be negative and all years after Christ will be positive.

So we have to live in the year 2020 and this Greek historian was born in the year - 484.
