Answer:
Step-by-step explanation:
Area = 84sqaure inch
Width = 2 1/2inch = 5/2inch
Area = l × width
So: 84 = l × 5/2
168 = 5l
l =>168/5
l = 33 3/5
There shouldn't be a negative in front of one of the equations.
Answer:

Step-by-step explanation:
The given function is:

We have to find the value of the function at x = -5/3
In order to do this we need to replace every occurrence of x in the given function by -5/3. i.e.

Thus, the value of the function at x =-5/3 is 
yes. The zero to the left of the decimal point does not affect the overall value of the problem when removed, since it is zero.
