The area should be 36.
The formula for area is base times height [A=b(h)]
The mean is the average of the numbers.
It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
For example: What is the Mean of these numbers?
6, 11, 7
<span><span>Add the numbers: 6 + 11 + 7 = 24
</span><span>Divide by how many numbers (there are 3 numbers): 24 / 3 = 8</span></span><span>The Mean is 8
Hope this helps :)</span>
The two planes intersect at line XY
Given that two planes named ABCD and EFGH.
These two planes are intersecting each other as shown in the figure.
By looking the figure it is obvious that two planes are intersecting each other at point X and Y.
Hence, the correct answer is XY
<span>If (x-2) is a factor of polynomial , f(x).Then, it means we can find the zeros or the solutions of the polynomial by putting f(x-2) = 0.Because, the zeros or roots of a polynomial is found by putting f(x)=0, where x is a factor of the polynomial.
Example, say f(x)= x^2-2
Which implies, f(x) = (x-2)(x+2)
Here, both x-2 and x+2 are the factors of the polynomial. So,x-2 = 0, we get, x=2 is a zero of the polynomial.</span>
