The answer is Option A because can be writen as
.
1. Use the FOIL method (x+9)(x+9)
First, outer, inner, last
Add your like terms
2. When you add or subtract polynomials you add or subtract the like terms and then put them in order from largest to smallest exponents.
3.
4. Since it is the perimeter, we add the 3 together.
Add the like terms together:
Put them in order of exponents

Answer:
<u>First question answer:</u> The limit is 69
<u>Second question answer:</u> The limit is 5
Step-by-step explanation:
For the first limit, plug in in the expression
, that's the answer for linear equations and limits.
So we have:
The answer is 69
For the second limit, if we do same thing as the first, we will get division by 0. Also indeterminate form, 0 divided by 0. Thus we would think that the limit does not exist. But if we do some algebra, we can easily simplify it and thus plug in the value into the simplified expression to get the correct answer. Shown below:
<em>Now putting 1 in gives us the limit:</em>
So the answer is 5
