Step-by-step explanation:

the absolute value is always positive. imagine it as "how much away from zero"
Ok so 5x20 is 100 and 3x20 is 60 then add 3 is 63 apps that she downloaded then 100-63 is 37 apps that she still has space for.
Hopefully this makes sense!
Hi,
First we must go back to the formula of the Area of a 2d figure which is L*W or Length times the Width. So, we could divide 64 by 16.
64/16 = 4
The answer is 4.
Formula for the area of a circle is Pi*radius squared
So, we do Pi*2^2 which is 12.57
