Answer:

No.

If two rectangles are congruent, it means they are the exact same shape and size.

I have uploaded an image with this answer. In the image, you can see two rectangles with the same perimeter. However, they are not congruent because they are not of the same size (even though they are of the same shape - a rectangle).

Hence, two rectangles may not be congruent if they have the same perimeter.

Suppose Y varies directly with X, and Y = 15 and X = 5. Write a direct variation equation that relates X and Y. What is the valu
Oksana_A [137]

Answer:

Step-by-step explanation:

If two variables are directly proportional, it means that an increase in the value of one variable would cause a corresponding increase in the other variable. Also, a decrease in the value of one variable would cause a corresponding decrease in the other variable.

Given that Y varies directly with X, and Y = 15 and X = 5, if we introduce a constant of proportionality, k, the expression becomes

15 = 5k

k = 15/5

k = 3

The equation would be

Y = 3X

Therefore, when X = 9, the value of Y would be

Y = 3 × 9

Y = 27

In still water, a boat averages 12 miles per hour. It takes the same amount of time to travel 14 miles downstream, with the curr
anyanavicka [17]
T is equal in both situations ... d = r X t   so d/r = t
c is rate of waters current

\frac{14}{12+c} = \frac{7}{12-c}
14(12 - c) = 7(12 + c)
2(12 - c) = 12 + c
24 - 2c = 12 + c
12 = 3c
4 = c     The rate of the waters current is 4 miles per hour.

d=2.3e^

divide both sides by 2
