The cost C(in dollars) of producing x widgets is represented by c=4.5x squared how many widgets are produced if the cost is $544.50
Answered by mathhelper
so 4.5x^2 = 544.5
x^2 = 544.5/4.5 = 121
x = √121 = ....
Answered by Neil
544.50 = 4.5x^2
544.50 / 4.5 = 4.5x^2 / 4.5
121 = x^2
sqrt (121) = sqrt (x^2)
11 = x widgets
