First find out how many cm at in an foot then convert it over to cm or feet. Then compare. The larger number is the wider car.
The function is described by the rule

.
The inverse function

is such that

.
Thus, since

, we have

.
Equating the two ways we expressed

, we have:

.
Rearranging, we have:

.
Answer: first choice: p(x)=7x-2
Step 1: find two numbers that multiply to give ac ( in other words a x c ) and add to give b
step 2: rewrite the middle with those numbers
step 3: factor the first two and last two terms separately
step 4: if you’ve done this correctly, your two new terms should have a clearly visible common factor
and then you’re done! hope this helps!
