The answer is c because 2.50 is hamburgers and so is x. X is the number of burgers and you multiply that by the cost and add it to the drinks which you find the same way
We are looking for k in the equation
(x+4)(x+k/4) = x^2+7x+k
The left hand side expands to:
x^2+(4+k/4)x+k = x^2+7x+k
Comparing coefficients for the linear terms, we have the equation
(4+k/4)=7
Solving for k:
16+k=28
k=12
Thus the number to be subtracted is 15-k=15-12=3
Answer:
It is a permutation problem. There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Step-by-step explanation:
In this case, the company will hire four <em>different</em> applicants from a group of 40 people for 4 <em>different</em> jobs. In this case, we need to consider the effect of order in the number of possibilities. Hence, we must use the permutation formula:
(1)
Where:
- Total of applicants.
- Selected applicants.
If we know that 
and 
, then the number of possibilities is:
There are 2193360 possibilities of selecting 4 candidates from 40 applicants when order of selection is considered.
Okay I'm not sure which you need help with but.
First one, it means how did you feel about how the worksheets were set up
Then, about what you learned
How you felt about tests
And for the last one you could say thing like
How you felt about obstacles, the teachers/professors, pressure, how much you think you learned, how you feel at the end of the school year versus the beginning, or how you grew as a student/person. You can pick one or two or your own, those are just some ideas.
How is this your last day at school? You are quite lucky
