Which of the following are solutions to the equation below?
evablogger [386]

Answer:

x = 5 ± \sqrt{17}

Step-by-step explanation:

Given

x² - 10x + 25 = 17 ← left side is a perfect square, thus

(x - 5)² = 17 ( take the square root of both sides )

x - 5 = ± \sqrt{17} ( add 5 to both sides )

x = 5 ± \sqrt{17}

Thus

x = 5 - \sqrt{17}

x = 5 + \sqrt{17}

shusha [124]
Use inverse proportion ratio: xy=k

(124)(7)=k
k=868 (this is our constant)

now substitute the constant into the inverse proportion ratio knowing the number of workers

28x=868

solve for x by dividing both sides by 28 to find the time it takes to build the house

x=31 days

so it will take 31 days for 28 workers to build the house
