Need help on this volume/surface area

8.

Imagine opening the Triangular prism

We will have 2 triangles at the base

and 3 rectangles

The sides of the triangle : base 9in, height 3in

Area of Triangle

   =

Now the rectangles

Rectangle1 with sides 9in and 15in, Area = 9*15 = 135

Rectangle 2 with sides 5in and 15in , Area = 5*15 = 75

Rectangle 3 with sides 6in and 15in, Area = 6*15 = 90

Now the total area of the prism

            =

answer: howdy

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
