Question

the product of two numbers is 3.92 if one number is double of the other then find the other​

Answer 1

Answer:

x = 1.4

2x = 2.8

Step-by-step explanation:

Let the first number be 'x'

other number = 2x

Now given,

x * 2x = 3.92

2x^2 = 3.92

x^2 = 3.92 ÷ 2

x^2 = 1.96

$x = \sqrt{1.96} \\ = 1.4$

x = 1.4

2x = 2.8
