A=12h(a+b) Solve for h.

Answer:

h=\frac{A}{12a+12b}

Step-by-step explanation:

Solve for h, means that you have <em>to clear</em> h.

We have the expression A=12h(a+b)

We can divide both sides of the equation in (a+b):

A=12h(a+b)\\\frac{A}{(a+b)}=\frac{12h(a+b)}{(a+b)}\\\\\frac{A}{(a+b)}=12h

Now divide again both sides of the equation in 12.

\frac{A}{(a+b)}=12h\\\\\frac{A}{12(a+b)} =\frac{12h}{12}\\\\\frac{A}{12a+12b} =h

Observation: Distributive property: c(a+b)=ca+cb, then: 12(a+b)=12a+12b

The answer is: h=\frac{A}{12a+12b}
