The area of a rectangular closet is 18 square feet. The perimeter is 18 feet. What are the dimensions of the closet?

Height: 6ft

Base: 3 ft    

Step-by-step explanation:

Factors of 18 are: 1, 2, 3, 6, 9, 18

18 and 9 are both two big because of perimeter...this rules out 2 and 1 because those are the factor pairs which leaves 6 and 3

Area = bh = 3*6 = 18

Perimeter is adding all the sides twice

(6*2) + (3*2) = 12 + 6 = 18

Area = 18 Correct

Perimeter = 18 Correct

the domain of a function is the set of input values, x , for which a function is defined. the domain is shown in the left oval in the picture below. the function provides an output value, f(x) , for each member of the domain.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
