A group of 53 tourists visit a museum. Museum volunteers lead tours for groups of no more than 8 tourists. Draw a model to show the least number of groups that can be formed for these 53 tourists. Use circles to show the groups and choose a symbol to show each person.

Total number of group formed = 7

Step-by-step explanation:

As given,

1 group has 8 people

Total people = 53

Let

Total number of group made = x

As 1 group = 8 tourist

⇒x group = 8x tourist

As Total tourist = 53

⇒8x = 53

⇒x = = 6.6

This means,

There are 6 full group of 8 people in each group = 48 tourist

and 1 group of 53-48 = 5 people.

So,

Total number of group formed = 7

In the diagram , Δ represent each person.

The figure  is as follows :

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
