Answer:
The least amount of numbers that he can work at his job to have enough for the headphones he wants is 17 hours.
Step-by-step explanation:
To find the number of hours you could divide the cost of the headphones by the amount he earns each hour so you would do $119/ 7 to get 17 and then you could check your answer with multiplication by multiplying 7 * 17 to get 119 which shows that he has to work at least 17 hours to get the headphones he wants.
$119 / 7 = 17
17 * 7 = 119

All you have to do is multiply them all.
3*3*4*2=72
Answer:
(x^4 - 9·x + 5·x^7) + (5·x - 10 + 3·x^4 - 2·x^2)
x^4 - 9·x + 5·x^7 + 5·x - 10 + 3·x^4 - 2·x^2
5·x^7 + x^4 + 3·x^4 - 2·x^2 - 9·x + 5·x - 10
5·x^7 + 4·x^4 - 2·x^2 - 4·x - 10
I am dumb so no heheheheeheh
