In Part A you chose an expression for the pattern that the numbers continue in. Part B is asking you to use that expression to find the 20th number in the pattern.

If the expression is 4n+4 and n represents the #th number then this is how you would solve the expression:

4(20)+4

80+4 = 84

So, the answer to Part B is 84.

The 20th expression would be 80. Counted on my fingers xD hit 80 when i did 20 fingers. which means that if you put 20 as n, it should come out to 80, but it comes out to 84 by the answer you chose, so I'm wondering if the answer you chose was right, or if it was A

A geographer found that the land area of Aruba is 75 square miles and the land area of Bermuda is 19 square miles. Based on thes

MakcuM [25]

The interpretation of x in the equation 75•x + 19•y = T, used by the geographer, based on the land area of Aruba, 75 m², and Bermuda, 19 m², is the population in a square mile of Aruba

<h3>Which method can be used to find the interpretation of x in the equation?</h3>

The land area of Aruba = 75 m²

Land area of Bermuda = 19 m²

The total number of residents is given in the question by the equation;

75•x + 19•y = T

Therefore;

x = The number of people in a square mile in Aruba

y = The number of people in a square mile in Bermuda

Which gives;

The interpretation of the variable, x in the context is the population of Aruba per square mile.
