PLEASE ANSWER WILL MARK BRAINLIEST A length of copper piping is in the shape of a triangular prism.
The triangle on its end is 9mm tall, 4mm wide. The piece of pipe is 18mm long. What is the surface area of the pipe?

please draw out the prism and show all working out​

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
