Answer:
c = bx/(x+1)
Step-by-step explanation:
Add cx to get c-terms together, and divide by the coefficient of c.
bx = cx + c
bx = c(x +1) . . . . factor out c
bx/(x +1) = c
It’s simple, do: 8+8+10+10, just add them you will get 36. The explanation is: Perimeter is add up all the sides, since it is a rectangle it has congruent sides, so they have the same length
Y=68+4x
100=68+4x
-68=-68
32=4x
Divide both sides by 4
x=it will take 8 min. for the water to reach 100 degrees
y=total degrees
x=# of minutes
