Answer:

Step-by-step explanation:
The Given question is INCOMPLETE as the statements are not provided.
Now, let us try and solve the given expression here:
The given expression is: 
Now, the BINOMIAL EXPANSION is the expansion which describes the algebraic expansion of powers of a binomial.
Here, 
or, on simplification, the terms of the expansion are:

The above statement holds for each n > 0
Hence, the complete expansion for the given expression is given as above.
Answer: Andy covers all the walls of his kitchen using 6 rolls of a wallpaper.
To Find:
Number of rolls used per wall.
Solution:
Since, we know that the shape of a kitchen is a cuboid.
And a cuboid has total 6 faces, with 4 walls, one roof and one floor.
So, total number of walls in Andy's kitchen = 4
Now, it is given that he uses 6 rolls of wallpaper to cover 4 walls completely.
In order to find the number of rolls used per wall, we'll have to divide the total number of rolls used with the total number of walls.
Number of rolls used per wall =
So, 1.5 rolls are used to cover one wall.

Answer:
(D) is the right answer
Step-by-step explanation:
The cross section will be a quadrilateral when the intersecting plane forms a closed four sided polygon along with the pyramid.
A triangular pyramid has four faces. So, to form four straight lines and therefore a quadrilateral, the intersecting plane must intersect all four faces.
A. In this case the plane will only intersect one side of the pyramid so four sided polygon can't be formed.
B. It will only intersect the two sides of the pyramid but the cross section will not be a quadrilateral.
C. In this case the plane will intersect three sides of the pyramid so the cross section will be a triangle not a quadrilateral.
D. In this case the plane intersects all the four faces forming a closed polygon of 4 straight lines so the cross section will be a quadrilateral.
So, the Correct Option is (D) : When the plane intersects the base and all three lateral faces of the pyramid, the cross section of the triangular pyramid will be a quadrilateral.
Answer:
90, 81, 72, 63, 54
Step-by-step explanation:
I think that these numbers make up the most possible product. Having the larger numbers on the side as the tens digit would be a better way of making the product bigger so that you can leave the smaller numbers for the smaller ones digit.
