Answer: the number is 5

Step-by-step explanation:

Let the number be x , then the square of the number means x^{2} .

Therefore:

x^{2} +3=28

subtract 3 from both sides

x^{2} = 28 - 3

x^{2} =25

find the square root of both sides

x = 5

Stella [2.4K]

Answer:

It's like adding whole numbers, but with a dot. add 75+75=150
