Question

A. Show all of your work to solve each equation and to check for extraneous solutions:2. 2[√(w + 4)]=5

Answer 1

The value of w is w = 9/4

EXPLANATION :

From the problem, we have the equation :

`2√(w+4)=5`

Divide both sides by 2

`√(w+4)=(5)/(2)`

Take the squares of both sides :

`w+4=(25)/(4)`

Subtract 4 from both sides :

`\begin{gathered} w+4-4=(25)/(4)-4 \\ w=(9)/(4) \end{gathered}`
