P=18
l=5 cm greater than the width
w=5 less than the length

USE YOUR NUMBER SENSE!!! - just plug in different number below 4 to figure out the width

3=w  3+5=8 8+8=16+6=22    WILL NOT WORK

2=w   2+5=7  7+7=14   14+2+2= 18    WE HAVE A WINNER!!!!

What is the greatest common factor of 48 and 64?
aleksklad [387]

Answer:

The GCF of 48 and 64 is 16

Step-by-step explanation:

To figure out GCF, you make a list of all the prime factors, pick out the numbers they have in common, and multiply them together.  In this case:

48:  2 x 2 x 2 x 2 x 3

64: 2 x 2 x 2 x 2 x 2 x 2

They have four 2's in common, so you multiply 2 x 2 x 2 x 2 =16

A band has 7 new songs and wants to put 5 of them on a demo cd. how many different arrangements of 5 songs are possible.
Vsevolod [243]
Actually, this question first involves COMBINATIONS and then PERMUTATIONS.

We first must calculate how many combinations can 5 things can be chosen from 7.
The formula is:
n! / r! *(n -r)! =
7! / 5! * 2! =
7 * 6 * 5! / 5 ! * 2 =
7 * 6 / 2 = 21 ways we can choose 5 things from 7 objects.

Now we must see how many permutations there are of 5 things:
5 * 4 * 3 * 2 * 1 =
120

That means we can put each of the 5 song combinations into 120 "5 song sequences". 
So, the total number of ways is
21 * 120 = 2,520 possible ways.
