What is the perimeter of the actual garden?

Lilit [14]

Answer: 576 inches or 48 feet

Step-by-step explanation:

set up a proportion where $\frac{drawing AB}{actual AB} =\frac{drawing perimeter}{actual perimeter}$

so you get drawingAB = 24 in

actualAB = 18 feet = 18 * 12 in = 216 in

drawing perimeter = 64 in

so plug these in to get $\frac{24}{216} =\frac{64}{actual perimeter}$

rearrange to get $actual perimeter = \frac{216 * 64}{24}$

and solve to get 576 inches or 576/12 = 48 feet

How do you do this ??

VikaD [51]

Answer:

(D)

Step-by-step explanation:

First, you have to graph the equation. Then you notice that it is a parabola facing downwards. This means that as the graph decreases on the left side, the x's become negative and the y's become negative. On the right side, the x's become positive and the y's become negative.
