Answer:

=  -  {m}^{2}  - 3n + 13

Step-by-step explanation:

- (m \times m + 3n - 13)

m \times m =  {m}^{1}  \times m

{m}^{1}  \times  {m}^{1}  =  {m}^{1 + 1} =  {m}^{2}

- ( {m}^{2}  + 3n - 13)

=  -  {m}^{2}  - 3n + 13

Avi uses 11 toothpicks to form a row of 5 attached triangles, as shown. Suppose he continues this pattern, using 89 toothpicks i
Pavel [41]

Answer:

44

Step-by-step explanation:

Given that Avi used 11 toothpicks to form a row of 5 attached triangles.

Total number of toothpicks used = 89

Let the total number of triangles formed be represented by x, so that:

11 toothpicks = 5 triangles

It would be observed that only the first triangle starting the pattern has 3 toothpicks. So that;

the average number of toothpicks for 1 triangle = \frac{11}{5}

                                  = 2.2

The number of toothpicks per triangle = 2.0

Thus,

x = \frac{89}{2.0}

  = 44.5

x = 44

The total number of triangles formed is 44.
