Answer:
The answer is A. $1.35
Step-by-step explanation:
Two $10 bills are equal to $20.
Your change is $7.85
So if you subtract $7.85 from $20 you will come up with $12.15.
$12.15 is how much money you spend on mini burgers.
You can then divide how much money you spent with how many burgers you bought.
12.15 divided by 9 gives us 1.35. So each burger was $1.35.
Answer:
D)4x + 6/(x + 1)(x - 1)
Step-by-step explanation:
A field is basically a rectangle, so to find the perimeter of our field we are using the formula for the perimeter of a rectangle

where
is the perimeter
is the length
is the width
We know from our problem that the field has length 2/x + 1 and width 5/x^2 -1, so
and
.
Replacing values:


Notice that the denominator of the second fraction is a difference of squares, so we can factor it using the formula
where
is the first term and
is the second term. We can infer that
and
. So,
. Replacing that:


We can see that the common denominator of our fractions is
. Now we can simplify our fraction using the common denominator:




We can conclude that the perimeter of the field is D)4x + 6/(x + 1)(x - 1).
