X represents the height of the leg of the coffee table, plug it in and we'll see
4(2x) + 4(x)
= 4 (2*coffeetableleg) + 4 (coffeetableleg)
= 4 (kitchentableleg) + 4 (coffeetableleg)
= total length of kitchen table legs + total length of coffee table legs
= Total length measurement of table legs needed to build a kitchen table and a coffee table

Step-by-step explanation:
We have been given the following expression for simplification;
The bases of the two expressions are the same. They are both equal to 4. When multiplying numbers with the same base, we simply add their exponents. In this case our exponents are;
4 and -9
adding them we have;
4 + (-9) = -5
The simplified expression thus becomes;

Answer: The percent higher is 41.68%. If 49 planes were selected, 20 of them should be above 15 years.
To find the percent, we first need the z-score.
(15 - 13.5) / 7.3 = 0.21
Now, use a normal distribution table to find the percent above a score of 0.21. It will be 41.68%.
To find the number of 49 planes above this value, multiply 49 by 0.4168. You will have about 20.4 planes.
