A rectangle has a length of (x+3) centimeters and a width of 1/2x centimeters. If the perimeter is 24 cm, what is the length of the rectangle?

17

Step-by-step explanation:

(X+3)+½x=24

1½x+3=24

1½x=24-3

1½x=21

x=14.

Length=14+3=17

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

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.
