A rectangle has a length x centimeters and a width that is equal to half its length. The perimeter of the rectangle is 50 centimetres. What is the length and width of the rectangle? no links just answer the question with a clear explanation and I'll give you

Step-by-step explanation:

Let x = length

Then width = (1/2)x

Perimeter = 2(length) + 2(width) = 54

                  length + width = 27

So, x + (1/2)x = 27

           (3/2)x = 27

                 x = 27(2/3) = 18     (1/2)x = 9

 length = 18 cm and width = 9 cm

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
