**Clear the fraction by multiplying both sides by 3.**

2(x+4)=24

Clear the parentheses.

2x + 8 = 24

Move the 8 to the other side.

2x = 24-8

combine terms

2x = 16

Divide both sides by 2

2x/2 = 16/2

x = 8

round the results to the nearest tenth and then to the nearest hundredth:

2. -57.124/10.104

3. -13.254(-3.145)**2 is**

-57.124/10.104 = -5.6535

I don't know what you've been taught on rounding (positive OR negative numbers) so I'll let this go.
