PLEASE ANSWER WILL MARK BRAINLIEST 30 POINTS 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​​

step-by-step explanation:

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
