Solve by taking square roots
X^2 +25 = 0

x = ± 5i

Step-by-step explanation:

x² + 25 = 0 ( subtract 25 from both sides )

x² = - 25 ( since negative the roots are not real )

Take square root of both sides

x = ± = ± = ± 5i

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
