Arectangular garden has a length of (3x + 30) units and a width of (x + 20) units. the garden also consists of a walkway, which has an area of (x2 + 30x + 200) square units. complete the polynomial expression that represents the total planting area in the garden.

2x^2 + 60x + 400

If you multiply the first two equations to find the total area of the garden, then you can subtract the size of the path from tha and then you'll have your answer Math is the best thing ever

1. A relation is a set from x to a set y is called a function if each element of c is related to exactly one element in y. That is,given an element c in c, there is only one element in y that x is related to.
2. You can set up the relation as a table of ordered pairs. Then, text to see if each element in the domain is matched with exactly one element in the range . if so you have a function
3. The domain is the set of all possible x-values which will make the function "work" and will output real y- values .When finding the domain , remember :the denominator (bottom) of a fraction cannot be zero .
4.
