What is the surface area of the rectangular prism? A) 184 in.^2
B) 348 in.^2
C) 174 in.^2
D) 432 in^2

Surface Area of a cuboid = 2(lb+bh+hl)

= 2[(9×6)+(6×8)+(8×9)] = 348 in²

hence, option B is right ...

Hope u got what u were looking for :D

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

graph of this function as shown below:
