When radicals (square roots) include variables, they are still simplified the same way. We just have to work with variables as well as numbers
1) Factor the radicand (the numbers/variables inside the square root). Factor the number into its prime factors and expand the variable(s).
2) Bring any factor listed twice in the radicand to the outside
Answer:
7 is the first one
5 is the second one
27.5 is the third one
Step-by-step explanation:
Arrange the numbers in ascending order and find the number in the middle
if there are two numbers in the middle, add them and divide by two to find the average
Hope this helps!

Mark has 18 shirts
Given that together they have 140 shirts.
x + 7x - 4 = 140
8x = 140 + 4
8x = 144

7x - 4
7 × 18 - 4
126 - 4
= 122
