Answer:
(b × h) ÷ 2
Step-by-step explanation:
The best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.
After solving for a variable in an equation, we can cross check to know if our answer is correct or not.
This can be done by plugging in or substituting the value of the variable g into the equation. In most cases, you will find the variable on both sides.
When you substitute, the value on the left must be equal to the value on the right. If during your check, the value on the left does not equal the value on the right, it simply means the check does not work.
<em>Two things might result to a </em><em>check </em><em>not working: </em>
- the answer is not correct, or
- you made a mistake while checking.
Therefore, the best explanation to given when checking for the value of g that you have found is:
C. Substitute the value for g on either sides of your equation to check the answer. If the check does not work, it is either the answer is incorrect or there were errors you made when checking.

Step-by-step explanation:
Calculation to Find two positive numbers
First step
Let the first positive number be a
Let the second positive number be b
Second step is to create the Equation
a^2+b= 54....... Equation (1)
b = 54-a^2........ Equation (2)
Third step is to find the product
Product= a(54-a)^2 = 54a-a^3
Fourth step is to differentiate
dP/dx = 54-3a^2
dP/dx = 0
Fifth step is to solve for 54-3a^2 = 0
Hence,
3a^2=54
a^2 = 18
Last step
a= √(18)
b= 54-(√(18))^2
b=54-18
b = 36
Therefore the two positive numbers are 36
