when you are adding two negative numbers, the sum is basically the two numbers added together but as a negative. when added together they create a larger negative number; ex. -2 -8 = -10 which is the same as 2 + -8 = -10. when you are multiplying two negative numbers, you are really just multiplying the numbers and they come out to be a positive. a negative times a negative is a positive. ex. -5 x -5 = 25.
Length of room = area / width
Length of room = 56/7 = 8 feet.
She will need 7 + 7 + 8 + 8 = 30 feet of border.
The answer is B. In 10 hours, the phone would completely lose its charge.
Y=-10(10)+100=-100+100=0
product means multiplication either
86n
or
86*n which are the same thing
3
1
390
x 42
-------
1282
1564
----------------
the answer would be 16380
Hope this helped :)
