Answer:

Step-by-step explanation:

The first set of parentheses is unnecessary, so it can just be removed.

To remove the second set of parentheses, you must distribute the negative sign that is to its left. It changes every sign inside the parentheses.

Now you combine like terms.


we have M is durectly porpotional to r^2
so M=(k)r^2
and when r=2, m=14
so 14=(k)(2)^2
k=14/4 =7/2
so when r=12
m= (7/2)(12)^2 =(7/2)(144) = 504
Answer:
< $0 --------------$35------ $50>
Step-by-step explanation:
I see it's still the same, the maximum discount can be put off is still $50
and you can find that out by discount 30% off 50 to get $35 :)
< $0 --------------$35------ $50>
the anwser would most likely be 3 because you want the LCM
It would be c because it is the only one that would fit into the number line
