<u>Given</u>:
The given expression is 
We need to determine how the expression can be simplified.
<u>Simplifying the expression:</u>
Let us determine how the expression can be simplified.
The expression is given by

Applying the exponent rule that
in the above expression, we get;

Adding the exponents, we get;

Again, applying the exponent rule
, we get;

Thus, the simplified expression is 
Hence, the expression is simplified by adding the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.
Therefore, Option D is the correct answer.
Ok so... W is week. It would be 20+2w. Because we start with the plants hight (20) and them it grows two cm per week, so 2w.
Answer:
$8.

See attached picture.
Answer:
AB = 21
Step-by-step explanation:
So we have two triangles (AEB and ADC), and they're similar by AA
Now, you can find the ratio of similitude by checking AE/AD which is 14/26 = 7/13
AB/AC = 7/13
Take AB as x aight
x/x+18 = 7/13
x=21
