I’m stuck pls help (use picture)

There are three unique sides to a rectangular prism. To find the surface area, we can find the area of each unique side and double it.

Side 1:

4 x 7 = 28

28 x 2 = 56

Side 2:

7 x 9 = 63

63 x 2 = 126

Side 3:

4 x 9 = 36

36 x 2 = 72

The surface area is the sum of all of the doubled areas of the individual slides.

SA = 56 + 126 + 72

SA = 254 in^2

Hope this helps!! :)

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
