Answer:
-5x
Step-by-step explanation:
Remember, if you multiply a negative number by a negative number, you will get a positive number, and positive numbers are greater than negative numbers. In this case, if I were to multiply each of these expressions with -1, I would get the following:
7(-1)+4=-3
-1-4=-5
5(-1)=-5
-5(-1)=5
And I'm sure you can imply how these values will correspond to other negative values. Basically, the last expression gives us a positive answer, which is larger than the others (which give a negative answer).
13x is the answer, you’re welcome.
If this helps shuttle A and B will leave at 4:40 together and shuttle B and C will leave at 5:00 together
So to work this out we need to find the 4th root of each of those and pick the one that gives an integer.
A:
This is a decimal therefore <em>not</em> an integer.
B:
Again a decimal, therefore <em>not </em>an integer.
C:
This is a whole number, so it <em>is </em>an integer.
D:
Decimal, therefore <em>not </em>an integer
E:
Again a decimal, <em>not</em> an integer.
The only one that gives an integer when put to the 4th root is C, therefore:
could be A^4, as the 4th root of it is an integer.
