Question 56288: please help i do not know how to convert this problem.
Perimeter of a rectangle
The width of the rectangular play ground is 2x-5 feet, and the length is 3x+9 feet. Write a polynomial p(x) that represents the perimeter and then evaluate this perimeter polynomial if x is 4 feet.
Answer by Cintchr(481) (Show Source): You can put this solution on YOUR website!
P(x) = 2 ( l + w )
l = 3x+9
w = 2x-5
x = 4
DO NOT plug x in yet. Even though this is a simple number, sometimes you will have a fraction or a decimal to plug in, and it is easier to combine like terms and multiply once, than to multiply several times and then add.
First combine like terms
Disxribute
NOW plug in the x
Multiply
