Answer:
n-2
Step-by-step explanation:
N sides polygon has n-2 triangles
Answer:
Extremely large and small numbers that have many zeros are long to write and take up a lot of room. So, by using scientific notation a number can be written shorter. For example, numbers such as 295,000,000,000 can be shortened to 2.95x
. This is easier to write and understand. This is why the scientific notation is used over standard.
9x-6-13x=94
-4x-6=94
-4x=100
x= -25
Yes, in the sense that the new area could be written as (x+1)^2 / 1.
Usually we would not bother with the "1" as divisor.
Let's actually do the work: what is the area of the square if we increase the side length of the existing square by 1 ft?
(x+1)^2 = x^2 + 2x + 1 (This is not a fraction, and thus not the ratio of
two integers, which, in turn, is the definition of
"rational number."
60, I think this is the right answer !
