mean is the same as avrage

Step-by-step explanation:

Answer:In mathematics and statistics, the arithmetic mean, or simply the mean or average when the context is clear, is the sum of a collection of numbers divided by the number of numbers in the collection. The collection is often a set of results of an experiment, or a set of results from a survey.

Answer:

1. -m(-8n^2-7n+1)

2. (2w+7c) (v+7c)

5. (q+3r)(q^2-3qr+9r^2)

7. x= - 4/7,  1/9

See below for additional problems and help.

Step-by-step explanation:

To factor polynomials, look for patterns and greatest common factors. When you remove these factors, write the factor and what remains.

For example:

  1. 8mn^2+7mn-m\\-m(-8n^2-7n+1)

Notice the term (-8n^2-7n+1) is left and is the term when the expression is divided by -m.

     2. Factor by grouping is similar. Pull out factors within pairs of term. Separate the terms by parenthesis. If the quantities in the [parenthesis are the same, the factoring has been successful.

(2vw + 7cv) + (14cw + 49c^2)\\v(2w+7c)+7c(2w+7c)

Notice that (2w+7c) is the same. The factoring is complete. The factors are:

(2w+7c) (v+7c)

3 - 6 is similar using specific forms for factoring. To find the forms, look in your notes or at resources on online. Here is one example.

      4. A sum of cubes has the form

a^3 + b^3 = (a + b)(a^2 -ab + b^2).

To use this form, take the cube root of each term. a = q and b=3r.

The factors are (q+3)(q^2-3qr+9r^2)

7-9 all involve factoring and then solving. You solve by setting the factors equal to 0.

7. (7x+4)(9x-1) = 0

(7x+4) = 0                      (9x-1)=0

7x=-4                               9x = 1

x= - 4/7                             x = 1/9

A triangle with a 135° angle​
GuDViN [60]

Answer:

The 135 external angle means its corresponding internal angle is (180–135) 45 degrees. The other internal angle of 65 plus the 45 is 110 degrees. Since the sum of degrees in the angles in a triangle is 180, the other interior angle is (180–110), or 70 degrees.
