Answer:
3 hours
Step-by-step explanation:
Let's express number of hours required for servicing as: x
The auto repair on First Street charges a flat fee of $15 plus $10 an hour for servicing a car.
This is expressed mathematically as:
$15 + $10 × x
= 15 + 10x
The auto repair shop on Second Avenue charges no flat fee but $15 an hour for servicing a car
This is expressed as:
$15 × x
= 15x
The number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at both shops is calculated as:
Charges by Auto repair shop on First street = Charges by Auto repair shop on Second Avenue
15 + 10x = 15x
15 = 15x - 10x
15 = 5x
5x = 15
x = 15/5
x = 3 hours
Therefore, the number of hours Malik's car needs to be serviced in order to be able to pay the same amount of money at either auto repair shops is 3 hours
Step-by-step explanation:
factor it: (start by factoring out the x that is common to all 3 )
next keep factoring the inside...
![= x\left(x^2+x-4x-4\right)\\=x \left[x\left(x+1\right)-4\left(x+1\right)\right]\\=\bold{x\left(x+1\right)\left(x-4\right)}](https://tex.z-dn.net/?f=%3D%20x%5Cleft%28x%5E2%2Bx-4x-4%5Cright%29%5C%5C%3Dx%20%20%5Cleft%5Bx%5Cleft%28x%2B1%5Cright%29-4%5Cleft%28x%2B1%5Cright%29%5Cright%5D%5C%5C%3D%5Cbold%7Bx%5Cleft%28x%2B1%5Cright%29%5Cleft%28x-4%5Cright%29%7D)
