C. You'd be starting at a higher floor (positive number) and descending floors (negative number per x). If you assume x is time it's a little more logical and visual.
Answer:165
Step-by-step explanation:
hope this helpsss
S= 2 (LW) +2 (LH) +2(WH)
then we can plug in the values we know! :)
S= 2(2*3) +2(2*4) +2(3*4)
Then we can do some simplifying
S= 2(6) +2(8) +2(12)
Then some more multiplying...
S=12 +16 +24
Then lastly, addition
S= 52 cm^2
3 outcomes are possible because you only have 3 games on it, and it is mandatory to only have 1 game and 1 song at a time.
2(x-7)/3=-2
3*2(x-7)/2*3=-2*3/2
x-7=-2*3/2
x-7=3*-1
x+(7-7)-7-3
x=7-3
x=4
