The model shows the expression 30 + 12.

Slav-nsk [51]

Answer:

4rth 6(5+2)

Step-by-step explanation:

This is because 6 rows of 5 squares means that there is 6 rows with 5 squares each. 6 × 5 = 30. Then there is another set of 6 rows with 2 squares in each, which is 6 × 2 = 12. 30 + 12 = 42. Which is why 6(5+2) = 42. 6(5+2) = 6(5) + 6(2) = 6(7) = 6 × 7 = 6 + 6 + 6 + 6 + 6 + 6 + 6 or 7 + 7 + 7 + 7 + 7 + 7 or 5 + 5 + 5 + 5 + 5 + 2 + 2 + 2 + 2 + 2 + 2 = 42.

Problem 1

<h3>Answers: n = 3 or n = 5</h3>

---------------

Work Shown:

$|4n - 15| = |n|\\\\4n - 15 = n \ \text{ or } \ 4n-15 = -n\\\\-15 = n-4n \ \text{ or } \ -15 = -n-4n\\\\-15 = -3n \ \text{ or } \ -15 = -5n\\\\-3n = -15 \ \text{ or } \ -5n = -15\\\\n = \frac{-15}{-3} \ \text{ or } \ n = \frac{-15}{-5}\\\\n = 5 \ \text{ or } \ n = 3\\\\$

Problem 2

<h3>Answers: c = 1 or c = -2/3</h3>

-----------------------

Work Shown:

$|2c+8| = |10c|\\\\2c+8 = 10c \ \text{ or } \ 2c+8 = -10c\\\\8 = 10c-2c \ \text{ or } \ 8 = -10c-2c\\\\8 = 8c \ \text{ or } \ 8 = -12c\\\\8c = 8 \ \text{ or } \ -12c = 8\\\\c = \frac{8}{8} \ \text{ or } \ c = \frac{8}{-12}\\\\c = 1 \ \text{ or } \ c = -\frac{2}{3}$
