A rectangle has a length of 8 and a width of x. Write a variable expression for the perimeter of the rectangle
natta225 [31]
Hi,

Since the perimeter of a rectangle is equal to twice the length plus twice the width, what you want to do here is P = 2(8) + 2(x) = 16 + 2x

Hope this helps! If my answer was not clear enough or you’d like further explanation please let me know. Also, English is not my first language, so I’m sorry for any mistakes.

List the sample space for rolling two dice and finding the sum of the numbers. How many 8's are there in the sample space? [Assu
Reptile [31]
Using the given assumption, there are 3.

The sample space for rolling two dice and finding the sum is:

2   3   4   5   6    7 
3   4   5   6   7    8
4   5   6   7   8    9
5   6   7   8   9    10
6   7   8   9   10  11
7   8   9  10  11  12

From the sample space alone, there are 5.  However, since a 3 and a 5 is the same as a 5 and a 3, this means that 2, 6 is the same as 6, 2 as well; this takes 2 off of the 5, leaving us 3.
