So there if 2 cars hold 14 you have to divide 14 by 2 to get 7. So then it says there are 12 cars. So then you have to multiply 7 by 12. To get 84.
14/2=7
12•7=84
Answer 84
Original cube side length is s = 4 inches, so the vol. is 4^3 in^3, or 64 in^3 = s^3.
If we double the original side length, we get S = 2s, and the new volume
is S^3 = (2s)^3 = 8s^3 = 8(64 in^3) = 512 in^3.
Answer: the new cube has a volume 8 times greater than the original cube has.
Answer:
it would be a rectangle
Step-by-step explanation:
it would be a rectangle because when you cut it in the cross section there will be four parell sides, so therefore it would have to make a rectangle because the side lengths would not be even.

<h3>Explanation:</h3>
Matrices can only be added if they are the same dimensions. Choices B and D have different dimensions than a 2×1 matrix representing a point. Choice C would translate the point to a position 1 unit up and 1 unit to the right of its original location.
![\left[\begin{array}{c}x\\y\end{array}\right] +\left[\begin{array}{c}0\\0\end{array}\right] =\left[\begin{array}{c}x\\y\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D%20%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D0%5C%5C0%5Cend%7Barray%7D%5Cright%5D%20%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7Dx%5C%5Cy%5Cend%7Barray%7D%5Cright%5D)
Answer:
10n-13+3y
Step-by-step explanation:
The only way to simplify is add like terms. This is an expression so no answer can be displayed.
n+9n=10 n
-10-3=-13
and 3y is by itself.
