3(x - 5) < -21 on a number line

  see below

Step-by-step explanation:

You can solve for x as follows:

Divide by 3:

  x -5 < -7

Add 5

  x < -2

This plots on a number line with an open circle at -2, and shading to the left.

_____

The circle is open because the value -2 is not in the solution set. Shading is to the left because all values less than -2 are in the solution set.

what is the question? i am guessing you are looking for the area.

to find an area, you have to do length x width.

in this case, it would be 12 ft x 4 ft = 48 sq. ft
