Answer:

First, look at the side lengths a, b, and c, where c is the longest. Then take the sum of a squared and b squared and compare it to c squared. If they are equal, the triangle is a right triangle. If c squared is less than a squared plus b squared, the triangle is acute. If c squared is greater than a squared plus b squared, the triangle is obtuse.

(it was the sample answer)

1) The side lengths of the triangles determine which of these types the triangle is:

a) equilateral if all the sides are equal

b) isoscels if two sides are equal and one is different

c) scalene is the three sides are different.

2) The side lengths determine the angles. When you know the three sides you can use the cosine law to determine the angles. The type of triangle according to the angles is:

a) acute if all the angles are less than 90°

b) right if one angle measures 90°

c) obtuse if one angle is greater than 90°

klasskru [66]

Answer:

Step-by-step explanation:

|3x+12|

one is as it is                                     one is the negative value of it

3x + 12                                                   - (3x + 12)

                                                               - 3x - 12

That is because both negative and positive values put in am absolute value become positive.

To find the mean you add all the numbers and divide by how many numbers there are so in this case 2+3+4+4+6= 19, there are 5 numbers so divide 19/5
