An electrical company uses the function f(h) = 15h + 75 to calculate the total repair bill, f(h), for h number of hours worked. find h if f(h) = $225. 10 hours 15 hours 3,375 hours 3,450 hours

10 hours

Step-by-step explanation:

f(h) =  15h + 75 = 225

subtracting 75 from both sides and simplifying:

15h +75-75 = 225-75 =150

15h = 150

Dividing both sides by 15:

15h/15 = 150/15

h = 10 hours

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
