Answer:
four magazines and two books
Step-by-step explanation:
3.50*4= 14
4*2= 8
14+8= 22
It's 4. The factors of 12 are: 1,2,3,4,6,12. The factors of 20 are: 1,2,4,5,10,20.
If you would like to simplify <span>(-2)-3 -8 - 8 and 6x - 2, you can do this using the following steps:
</span><span>(-2)-3 -8 - 8 = - 2 - 3 - 8 - 8 = - 5 - 8 - 8 = - 13 - 8 = - 21
6x - 2 = 2 * (3x - 1)
The correct result would be - 21 and </span><span>2 * (3x - 1).</span>
