Answer:
5 + 2.5x <20
Step-by-step explanation:
subtract 5 from each side so now it is 2.5x < 15
divide both sides by 2.5, so now it is x < 6
so it will be LESS THAN 6 months before her hair is LESS THAN 20 centimeters
Answer:
so you would swap places with y, [x]
remove the square part and place it with the opposite of squaring, is square rooting.
and the / stands for [division] so change that to multiplication
x = y square root muliplied by a

The answer:
radical number is sometimes called, irrational number. Radical number is inside the specific symbol √. For example, √a is called square root of a, for all value positive of the number a.
According to our case, there are five choices, among these, the numbers which can be called as radical are
3x√x²y , x√xy²,
proof:
3x√x²y = √9x²x²y= √9x²√x²y, and we know that √9x² = 3x, so √9x²√x²y= 3x√x²y
x√xy² =√x²xy² , and we know that √x² = x, so √x²√xy²= x√xy²
