Please help me out I don’t understand I’ll give more if right

x = 15.

Step-by-step explanation:

We apply the tangent-secant theorem:

18^2 = 12(12+x)

324 = 144 + 12x

12x =  324 - 144 = 180

x = 180/12 = 15.

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|
