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.

Have many times does 246 go into 6
eduard
None. If you think about it, 246 is greater than 6, so how can fit 246 into 6? Think about it this way . . how many times can you fit an elephant into a garden hose? . . yeah . . you probably can't . . try reposting your question . . and try making more sense of it next time. :)
