  $465

Step-by-step explanation:

The problem statement tells you h represents the number of hours, and the number of hours is 7.

It also tells you f represents the number of fixtures, and the number of fixtures is 9.

And, the problem statement tells you the charge is 15h+40f, which is 15 times the number of hours plus 40 times the number of fixtures. Then the charges are ...

  15·7 +40·9 = 105 +360 = 465

Ben Frank charges $465 for the work.

if it wants an equation, 105h+360f but if its all together then its 465$

Step-by-step explanation:

15x7=105h

40x9=360f

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
