Question

A=A^2-3(2/5bh) solve for h

Answer 1

Answer:

$h=\frac{5}{6b}(A^2-a)$

Step-by-step explanation:

we have

$a=A^2-3(\frac{2}{5}bh)$

Solve for h

To "solve" means to find the value of a variable for which this equation is true

so

Isolate the variable h

Multiply by -1 both sides

$-a=-A^2+3(\frac{2}{5}bh)$

Adds A^2 both sides

$A^2-a=\frac{6}{5}bh$

Multiply both sides by 5/6

$\frac{5}{6}(A^2-a)=bh$

Divide by b both sides

$h=\frac{5}{6b}(A^2-a)$
