Answer:
If there is a negative tile and a positive tile, it creates a zero pair.
Like terms can occur with the same variables (except for terms with exponents)
Step-by-step explanation:
Answer:
6/95.
Step-by-step explanation:
Prob(red marble on the first choice) = 4/(10+6+4)
= 4/20
= 1/5.
Prob(green marble on the second draw) = 6/19.
Prob( read then a green)
= 1/5 * 6/19
= 6/95.
Just add them all up and divide by how many numbers there are
6+12+22+16=56
56 divided by 4 = 14
14 is the mean
Given: an n-gon
Prove: The sum of the measures of the interior angles is 180(n – 2)°.
Complete the missing parts of the paragraph proof.
We are given an n-gon, which has n sides and n vertices.
Answers:
1. If we choose one of the vertices, we can draw <u>n-3</u> diagonals.
2. These diagonals form <u>n-2</u> triangles.
3. The sum of the interior angle measures of a triangle is <u>180</u> degrees.
4. <u>n – 2</u> triangles would have an interior angle measure sum of <u>180</u> degrees.
5. Therefore, the sum of the measures of the interior angles of an n-gon is 180(n – 2)°.
Answer:
x = 20
Step-by-step explanation:
By exterior angle theorem, we have:
