Answer:
84 possible paths
Step-by-step explanation:
Given
--- 3 blocks north
--- 6 blocks east
Required
Number of distinct path
To solve this question, we make use of the following formula

The above formula implies that;
On a single path, there is a total of m + n steps to get to a particular position, where each path is either in m direction or n direction.
In this case:


So, we have:


Apply combination formula


Expand the numerator


Expand the denominator



<em>Hence, there are 84 possible paths</em>
<em></em>
<em> will also give the same result</em>
Yes, its also an integer, rational and real number
Equilateral is equal on all 3 sides
Isosceles has 2 congruent sides
Scalene is all three different
Answer:
55
Step-by-step explanation:
Its not that hard actually if you break down the exponents and then multiply and add them all together.
A = a + b over 2
First multiply both sides by 2:
2A = a+b
Now subtract a from both sides:
b = 2A - a
