Make h the subject of the formula:
d=√(3h/2)

Do you mean d = √(3h/2)?

Square both sides:

d² = √(3h/2)²

d² = 3h/2

Then, multiply both sides by 2/3 to obtain:

h = 2d²/3

I hope this helps!

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
