Simply move -2 to another side.

Distribute -1/3 in (x+6)
---> Answer
Answer:
16
Step-by-step explanation:
use the formula (b/2)^2 to find what number to add to each side of the equation
Answer:5 units
Step-by-step explanation:
Area(a)=30
Base(b)=12
Height(h)=?
Area of =(base(b) x height(h))/2
30=(12 x h)/2
Cross product
30 x 2=12 x h
60=12h
Divide both sides by 12
60/12=12h/h
5=h
Therefore height(h)=5units
