In the diagram below, what is the equation that represents the relationship between the number of triangles and the perimeter of
Marina86 [1]

Answer:

The perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

Step-by-step explanation:

According to the diagram, we get the following facts:

i) For one triangle (x=1), the total perimeter is (y=2\cdot 3 + 1\cdot 4 = 10).

ii) For two triangles (x = 2), the total perimeter is (y = 2\cdot 3 +2\cdot 4 = 14)

iii) For three triangles (x = 3), the total perimeter is (y = 2\cdot 3 +3\cdot 4 = 18)

iv) For four triangles (x = 4), the total perimeter is (y = 2\cdot 3 +4\cdot 4 = 22)

From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

Solve the equation.<br><br> 5d = 17.1<br><br><br> 12.1<br><br> 22.1<br><br> 85.5<br><br> 3.42
Rudiy27

Hello there!


5d = 17.1

The equation is asking you to find the value for "d". How to do that? Well, all you have to do is divide both side by 5.

5d/5 = 17.1

d = 3.42  

That's your answer!


You can even double check your work, if you want to. How? Well, you just need to replace 3.42 where it belongs.

5(3.42) = 17.1

17.1 = 17.1

True!


Let me know if you have additional questions. As always, it is my pleasure to help students like you!
