What is the total surface area of the rectangle prism? Help me please someone ASAP!

B) 256

Step-by-step explanation:

w = 4

l = 12

h = 5

Formula:

SA = 2(wl + hl + hw)

SA = 2(4*12 + 5*12 + 5*4)

SA = 2(48 + 60 + 20)

SA = 2(128)

SA = 256

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

what are ur choices?
