To solve this problem, you need to have x alone on one side of the inequality.  To do this, you need to undo the multiplication that is bonding 3 and x together.  To undo this, you need to divide both sides by 3.

This results in the inequality x<7.

Your final answer is x<7.

What is the area of the figure?<br><br> A.234 in.^2<br> B.315 in.^2<br> C.225 in.^2<br> D.252 in.^2
saul85 [17]

Let's imagine we enclosed the entire shape in a 15 inch wide, 21 inch tall rectangle, area 315 sq inches.

From that rectangle we have to take away the 3x6 bottom left corner, and a strip 21-6=15 inches long and 3 inches wide on the right.

A = 15×21 - 3×6 - 3×15 = 315 - 63 = 252 sq in

Answer: D.   252 inches squared, last choice
