Answer:

Step-by-step explanation:
You want x alone on the left side.
x is being multiplied by 3 and by c.
The opposite operation of multiplication is division. You must divide 3xc by 3c to end up with just x.
You must do the same operation to both sides of an equation, so divide both sides by 3c.

Divide both sides by 3c.

Simplify both sides.

Answer:
Polar bear babies are called cubs.
Step-by-step explanation:
They are born in the winter, usually in January or December. When first born, a polar bear cub weighs only 1 pound. It can't hear or see and has very little fur
Assuming that I am properly understand your question, all you have to do is get the initial values for each individual and add their savings monthly.
Starting
Josie: 80
Addie: 60
One month
Josie: 110
Addie: 100
Two months
Josie: 140
Addie: 140
So two months would be the answer.
You could also do...
x = months
80 + 30x = 60 + 40x
20 + 30x = 40x
20 = 10x (Divide by ten on both sides)
2 = x
2 Months

Expand,

=

So the third choice would be your answer!
Hope this helps!
Answer:
x=2, perimeter=14
Step-by-step explanation:
Finding x
(x+1)(x+2)
x^2+2x+x+2=12
x^2+3x-10
x^2-2x+5x-10
x(x-2)5(x-2)
(x+5)(x-2)
x=-5
x=2
Length or Width should be a positve number.
x=2
Perimeter:
3+3+4+4=14
