It must have snowed for 6 days in november.
HOW TO:
* there are 30 days in november. So convert 20% to a decimal, which is 0.2, and multiply that by 30.
30 x 0.2 = 6
20% of 30 days is 6 days.
Answer:
An extraneous solution is a root of a transformed equation that is not a root of the original equation because it was excluded from the domain of the original equation. Example 1: Solve for x , 1x − 2+1x + 2=4(x − 2)(x + 2) .Set the equation to equal zero. (this ends up being √x+4−x+2=0 )
Plug this into the y= button on your TI-83/84 calculator.
Find the value of each of your solutions (go to 2nd->Calc->Value and enter your solution for x )
You should get zero as an answer for each of them.
Step-by-step explanation:
Extraneous solutions are not solutions at all. They arise from outside the problem, from the method of solution. They are extraneous because they are not solutions of the original problem. ... To tell if a "solution" is extraneous you need to go back to the original problem and check to see if it is actually a solution.
Complete Question:
Lucas is planting grass on the shaded portions of the yard. What will be the total area of covered by grass? Fill in the missing.
Part A= 12 x ? = ? ft²
Part B= 0.5 x ? x 9 = ?ft²
Part C= 0.5 x 7 x ? = ?ft²
Total Area= ?ft²
Answer:
Step-by-step explanation:
Given
See attachment
From the attachment;
Part A is a rectangle with dimension 9ft by 12ft
So,
Part B is a triangle with dimension: height = 6 and base = 9
The height is calculated as:
And the base is:
So, the area is:
Part C is a triangle with dimension: height = 7 and base = 7
So, the area is:
Total Area is:
Only one number is odd,
Only 5 is a prime number,
Answer:
10(2x22) is not an example of distributive property. That would equal 10x44 not 12x22
