Simplify by factoring. What are the excluded values? Choose all that apply.
makvit [3.9K]

Answer:

x = -2

x = 8

Step-by-step explanation:

Excluded values are the ones which make the denominator zero

3x² + x - 10

3x² + 6x - 5x - 10

3x(x + 2) - 5(x + 2)

(x + 2)(3x - 5)

x² - 6x - 16

x² - 8x + 2x - 16

x(x - 8) + 2(x - 8)

(x - 8)(x + 2)

[(x + 2)(3x - 5)] ÷ [(x - 8)(x + 2)]

(3x - 5)/(x - 8)

So excluded values are 8, -2

A basketball team played six games. In those games, the team won by 7 points, lost by 7, won by 8, won by 9, lost by 4, and won
Gemiola [76]

Based on the difference in scores for the basketball team over the six games, the mean difference in scores was 3

<h3>How to find the mean difference in scores?</h3>

The basketball team had 6 games and in these games, their scores were listed as differences in game scores.

The mean of these differences in scores can be found by adding the differences where they won and subtracting the differences where they lost and then dividing by the number of games:

The mean difference in game scores is:

= (7 - 7 + 8 + 9 - 4 + 5) / 6

= 18 / 6

= 3

What is 8(3+a)? Please answer
alisha [4.7K]

The Answer is

<h2>24 + 8a</h2>

or, 8a + 24

To get the answer we have to distribute the 8, which means we have to multiply both terms in the parentheses by 8.

8 x 3 = 24

8 x a = 8a

So the answer is 24 + 8a
