If 39 is added to a number, it will be 4 times as large as it was originally. What's the number?

117

Step-by-step explanation:

Let the added number be (x)

39 + x = 39 × 4

x = 156 - 39

x = 17

13

Step-by-step explanation:

let the number=x

x+39=4x

39=3x

x=39/3=13

Check: 13+39=52

             4*13=52

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
