Question

Jason chooses a number that is the square root of four less than two times Amy’s number. If Amy’s number is 20, what is Jason’s number?

Answer 1

Answer:

• Jason's number is 6

Given :

• Amy's number is 20
• Jason's number is square root of four less then 2 times Amy's number

Step-by-step explanation:

${\small{\tt{Jason's \: \: number = \sqrt{ 2(20) -4}}}} \\ {\small{\tt{\implies{Jason's \: \: number = \sqrt{ 40 - 4}}}}} \\ {\small{\tt{\implies{Jason's \: \: number = \sqrt{36}}}}} \\{\small{\tt{\implies{Jason's \: \: number= 6}}}}$

${\small{\underline{\boxed{ \red{\frak{\therefore\ Jason's \ number = 6}}}}}}$
