(x+1)(x+2)(x+3)

=(x^2+3x+2)(x+3)

=x^3+6x^2+11x+6

For the first one to be true, the lowest term is x^3, leaving only three possible terms. I don't think there is a solution to this equation.

First equation multiplied by -5: 2y-10x=22

Add equations: -7x=14.

Solution to system B: x=-2,y=1

Solution to system A: x=-2,y=1

The solutions to the systems are the same, so the answer is B

Types: Toyota,Ford,Honda,Nissan,unknown

License plate ends with: 3,5,7,9

starts with: A,B,C

Colors: blue,green,yellow,red,unknown

Alice: blue,Toyota

Bob:yellow, ,B

Charlie: red, 

David: green (because the other color is not given and the problem has an answer)

If David has the Nissan, then he is parked next to the Ford. Say that Bob has the Ford. Then Charlie has the Honda, and the mysterious owner with the mysterious car and the license plate ending in 9 is next to him. No contradictions are found here, so David has a green Nissan.

There are 8 red tiles, since there is a red

wood triangle, square, pentagon, circle

plastic triangle, square, pentagon, circle.

Steve: 1/3

Ellen: 7/23

Multiply to get:

7/69

Since a=b is a solution, all possible values of ab, a+b, a, and b are every real number.

Try to find what will produce -7 to get the answer to the question. If you think that x is smaller than -3, try various values of x. Will it work? Then try 21+x. This will be too high for any x in the given range. Then try the last equation. Once you have found what value of x will produce -7 for each equation, find which one is in the given range.

I have noticed that you have not included a diagram. Here is how to include one: right click on the image and select 'open image in new tab'. Copy the URL from the top of the page. Then, go here and click the Image button. Paste the URL into the URL blank, type 'none' into the Alternative Text blank, and the image will show up. I will attempt to answer this if you can include an image.

There are no ways other than 1,2,3,4,5,6 to do this. I have proved this in another answer.

Since the number of people is not given, assume that the total number of people is n and the committee will have r people. Then the answer is \(\begin{pmatrix} n\\ r \end{pmatrix}\).

The amount of cubic feet in the slab is 16*16*1/2=16*8=128. Multiply 128*$15 to get the final answer.
