Answer:
Oh that's easy! You find out what the radius is.. then the diameter is another one of that number. Example say that the radius is 10 then the diameter is 20 or if the radius is 7 the diameter is 14
Step-by-step explanation:
So 7 friends with similar. Phone plans. 3 of them pays an extra 4 bucks, so that means that x+ 4 is what 3 of the 7 r paying. The other 4 pay just x Amt of money for their plan. So go find the total bill, it would be (x+4)+(x+4)+(x+4)+x+x+x+x. Now simplify, (x+4)^3, because there are three of the 7 using that, and then x^4, because 4 of the 7 r using that plan. So in total it would be (x+4)^3+ x^4. Hope this helps
-5-5/-1-1=
-10/-2=
5
y-5=5(x-1)
y-5=5x-5
y=5x+0
