Answer:

Step-by-step explanation:
So we have:

Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.
The denominators are 3 and 7.
The LCM of 3 and 7 is 21. Thus, multiply everything by 21:

Distribute:

Simplify the fractions:

Add 12x to both sides:

Subtract 9 from both sides:

Divide both sides by 26:

Reduce:

And that's our answer :)
Answer:
x² + 3x - 28
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor
(x + 7)(x - 4)
= x(x - 4) + 7(x - 4) ← distribute both parenthesis
= x² - 4x + 7x - 28 ← collect like terms
= x² + 3x - 28
Answer:
Step-by-step explanation:
Answer: She is correct because the average of the numbers 2, 3, 1, 4, 5, 2, 3, 4, 3, is 3.
Step-by-step explanation:
To find average you add all of the listed numbers, (2, 3, 1, 4, 5, 2, 3, 4, 3) which is 27. You then divide 27 by the amount of listed numbers, which is 9. 27 divided by 9 is 3. There for the average amount of strokes it takes to hit the ball into the hole of each green is 3.
