Yes, all numbers are real numbers because a number is a number, and nothing can change that. I hope this helps you!
30 + 18x is equivalent to 6(5 + 3x)
This is equivalent because of the distributive property. Multiply 6 by 5 and 3x to get your answer!
|a| = a for a ≥ 0
examples
|2| = 2, |4| = 4, |234| = 234, |1/2| = 1/2, |0| = 0
|a| = -a for a < 0
examples
|-4| = -(-4) = 4, |-6| = -(-6), |-123| = 123, |-4/5| = 4/5
|5 - 15| = | - 10| = 10
0 × |-6| = 0
Ignore the triangle on the top. i am sure that the correct answer.
