Answer: 60 days
Step-by-step explanation:
To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:
Multiple of 15 = 15, 30, 45, 60, 75, 90
Multiples of 20 = 20, 40, 60, 80, 100
Lowest common multiple = 60
Therefore, they'll be Washing the car on thesame day on the 60th day.
Answer:
the answer is 6
Step-by-step explanation:
you take the absolute value for both of them which is 2 and 8 but you keep the negative still so it would be -2+8 which is 6
Answer:
d. x ∈ {-3, -2, 1}
Step-by-step explanation:
The word "approximate" in the problem statement suggests that the roots may not be integers. Consequently, the solution method of choice is graphing.
A graph shows the solutions to f(x)=0 to be x=-3, x=-2, and x=1, matching selection D.

<em>Comment on the problem statement</em>
Any value of x can be put into the formula and it will be a "solution." For example, f(0) = -6 is a "solution" to the polynomial function. The problem statement is not specific as to the solution(s) sought. We have had to guess that we want values of x such that f(x)=0.
