Answer: b=2A/h.

First, multiple both sides of the equation (A=1/2bh) by 2. You should be left with bh=2A.

Divide both sides of the equation by h. You should be left with b=2A/h.

Hope that helped!

How can i simplify<br><img src="https://tex.z-dn.net/?f=25%20-%20%28%20%5Csqrt%7B16%7D%20%20-%201%29%20%5Ctimes%20%283%20-%209%2

We will use PEMDAS rule to simplify the given expression.

PEMDAS rule is given by:

P
-Parentheses first

E
-Exponents (ie Powers and Square Roots, etc.)

MD-Multiplication and Division (left-to-right)

AS
-Addition and Subtraction (left-to-right)
25-(\sqrt{16} -1) * (3-9) *2

Step 1: P-parenthesis first.

(3-9) is -6

√16 -1 = 4-1 =3

So new expression becomes : 25-3*(-6)*2

Step 2:

Multiplying (-3)*(-6)*2

We get +36

So new expression becomes : 25 +36

Step 3: Addition

Adding 25 and 36 we get 61

So final answer is 61 .
