4) Determine the solution. Show your work.
17 + x2 = 42

Work Shown:

17 + x^2 = 42

x^2 = 42-17

x^2 = 25

x = sqrt(25)  or  x = -sqrt(25)

x = 5 or x = -5

$93.38

Step-by-step explanation:

To solve this, we simply multiple $373.50 by 25% to figure out how much Mr.Hall pays for health insurance each month. Don't forget that we need to change 25% to its decimal form (25% -> 0.25).

$373.50 x 0.25 = $93.38

Mr.Hall must pay $93.38 dollars a month for his health insurance.
