The answer is C: 
Starting with the given formula for the area, A = 1/2hb, the first step is to isolate h by using the multiplicative inverse of b, which is
on both sides of the equation:

The result will be:

The last step is to use the multiplicative inverse of
, which is 2 or
to further isolate the variable <em>h </em>:

The formula for h will be:
which is the option C in your question.

Answer:
x= 5
Step-by-step explanation:
You need to get rid of the fraction first and to do that you muliply the whole equation by 5 so that your new equation reads 4x+25=45. Then you subtract 25 from both sides so you have 4x=20. Divide both sides by 4 so x=5.
Answer:
n<2
Step-by-step explanation:
-2n+5>1
-2n>1-5
(-2n>-4)divide by -2
NO. Sine is opposite/hypotenuse, so the answer should be 24/25
