Question

a rectangle has a length of 6x^3 y^2 - 1 and a width of 3xy+2.The formaula for the perimeter of a rectangle is P=2l+2w ,where l is length and w is the width.What is the perimeter of the rectangle?Simplify your answer.

Answer 1

Whatever the perimeter is, it will be in the form of an expression, rather than an actual number. It gives you a hint: Simplify your answer. This reveals that the answer will definitely be an expression.

All you have to do is substitute l = 6x^3y^2 - 1 and w = 3xy +2 into the formula P = 2(l + w) and then simplify.

Answer 2

i really dont get it :(

Answer 3

thanks

Answer 4

You'll realize that with math, the answer will not always be given to you and you will have to figure it out on your own.

Answer 5

If someone gives you a hint, you should at least try

Answer 7

P = 2l + 2w
P = 2(l + w)
P = 2(6x^3y^2 - 1 + 3xy + 2)
P = 12x^3y^2 - 2 + 6xy + 4
P = 12x^3y^2 + 6xy + 2
P = 2(6x^3y^2 + 3xy + 1)
