2x4 is the answer to 4x-2=38
Answer:

Step-by-step explanation:
Given the expression
.
we have to find the simplest form of the expression.

=
=
=
which is the simplest form of the given expression.
Solution:
we have been asked to find
If you ran exactly one mile, how many feet did you run.
It mean , we will have to convert miles in feet.
As we know that
1 mile is equivalent to 5280 feet.
Hence , we can use this conversion to get the exact value of miles in feet.
If you ran exactly one mile,it mean you ran exactly for 5280 feet.
3 + 1.75m
This represents 1.75 per mile plus a one time 3 charge.
Another way this can be written is
(1.75m + 6) - 3
This is a less efficient way, but represents the same. It is 1.75 per mile, this is plus 6, therefore we add the -3 outside the parenthesis so it evens out to +3 as the base charge.
Example: Lets say its 3 miles.
3 + 1.75 (3) = 8.25
(1.75 (3) + 6) - 3 = 8.25
