We just need to get the perimeter of the backyard.
Whole rectangle: length = 7ft ; width = 5 ft
Perimeter = 2(7+5) = 2(12) = 24 ft
Answer:
y = 3 (4)^x
Step-by-step explanation:
quadruples means multiplies by 4
This equation is in the form
y = ab^x where a is the initial amount and b is the amount we multiply by
y = 3 (4)^x
See attached graph.
The y-intercept is (0, 1), since the line is at that point when it intersects with the y-axis.
The common ratio is 1/4, since the y value multiplies by 1/4 for each unit on the x-axis.
