Answer:

24s^2, 54s^2, 96s^2

Step-by-step explanation:

Let s represent the initial side length of the cube.  Then the area of each face of the cube is A = 6s^2 (recalling that the area of a square of side length s is s^2).

a) Now suppose we double the side length.  The total area of the 6 faces of the cube will now be A = 6(2s)^2, or 24s^2 (a 24 times larger surface area),

b) tripled:  A = 6(3s)^2 = 54x^2

c) quadrupled?  A = 6(4s)^2 = 96s^2

atroni [7]

Answer:

1,114 people

Step-by-step explanation:

The equation y=19.43x+609.077 is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.

To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.

From 2000 to 2026,

2026-2000=26yrs

have passed.

The expected number who will attend the fair in 2026 is

y=19.43*26+609.077

y=1114.26

To the nearest whole number 1,114 people will attend in 2026
