Answer:
Step-by-step explanation:
The area of a rectangle can be found with the formula 
, where 
is the length of the rectangle and 
is the width.
From the given problem statement, we know that 
and 
, so we can fill in those values in the formula anbd solve for to get the width:
Divide both sides by 
to isolate by itself:
That is going to be 48 for the first question because 6x8 equals 48
Answer:
2
----------
5w^11
Step-by-step explanation:
8/20 reduces to 2/5, and (w^(-2)) / w^9 becomes 1 / w^11.
Overall, #20 reduces to:
2
----------
5w^11
Recall the rule of exponents:
w^a
----------- = w^(a-b)
w^b
and note that
w^(-2)
------------ = w^(-2-9) = w^(-11) (same as above)
w^9
<span>fixed annual membership fee of $20
</span><span>$2 per video game rented.
</span><span>Let f(n) represent the total annual cost of renting n video games
so
f(n) = 20 + 2n
if </span><span>increased by $15 the next year
then
f(n) = </span>20 + 2n + 15
f(n) = 2n + 35
answer
<span>f(n) = 2n + 35 (first choice)</span>
