Answer:
first and third
Step-by-step explanation:
Emma used the product instead of the quotient and forgot the parentheses in x-4.5
We are given
The equation that models this trip is T= 36x + 60
T represents the total cost for the group to take the trip and
X equals the number of people going
we know that
Domain is all possible values of x for which any function is defined
Since, number of people can neither be negative nor in decimals
so, x can not be negative or in decimals
now, we will check each options
option-A:
x=40
This is positive and whole number
so, this can be domain
so, this is TRUE
option-B:
x=60
This is positive and whole number
so, this can be domain
so, this is TRUE
option-C:
0< x< 40
It also includes decimals numbers
and we know that
x can not be in decimals
so, this is FALSE
option-D:
0< x< 39
It also includes decimals numbers
and we know that
x can not be in decimals
so, this is FALSE
The number of kilometers she will have left to run to finish the race is 0.9 km.
<u>Given the following data:</u>
- Speed =
To determine the number of kilometers she will have left to run to finish the race:
First of all, we would calculate the distance she has covered by using this formula;
Distance = 12.6 meters.
<u>For the </u><u>distance left</u><u>:</u>
Distance left = 0.9 km.

I got 168 because if you multiply 8x12 then you would get 96 and on the sides u need to multiply 3x12
I first would rearrange the problem
-220x^2 + 20x + 600x
Simplify
-220x^2 + 620x
Find the GCF of the two values
20x(11x + 13)
Hope this helps!
