The total length was 6 m.

One of the tables was 1.8 m

Subtract 1.8 from 6 to find the total length of the other two tables:

6 - 1.8 = 4.2m

The other two tables are the same size, so now divide 4.2 m by 2:

4.2 / 2 = 2.1

The other tables are 2.1 m long.

Answer:

12. a = 2

13. x = \dfrac{4}{3}

Step-by-step explanation:

12.

6a(a + 3) = 2a(3a + 5) + 16

First, distribute 6a on the left side, and distribute 2a on the right side.

6a² + 18a = 6a² + 10a + 16

Subtract 6a² from both sides.

18a = 10a + 16

Subtract 10a from both sides.

8a = 16

Divide both sides by 8.

a = 2

13.

\dfrac{1}{3}x + \dfrac{1}{2}x = \dfrac{1}{3}(x + 2)

The LCD of 2 and 3 is 6. We multiply both sides of the equation by 6 to get rid of all denominators.

6 \times \dfrac{1}{3}x + 6 \times \dfrac{1}{2}x = 6 \times \dfrac{1}{3}(x + 2)

\dfrac{6}{3}x + \dfrac{6}{2}x = \dfrac{6}{3}(x + 2)

2x + 3x = 2(x + 2)

Combine like terms on the left side. Distribute the 2 on the right side.

5x = 2x + 4

Subtract 2x from both sides.

3x = 4

Divide both sides by 3.

x = \dfrac{4}{3}
