There are three steps:<span>Rearrange the equation so "y" is on the left and everything else on the right.Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)<span>Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).</span></span>
angles x y z are all acute because they are less than 90 degrees

B: step 2
You need to multiply the 7 with the 4.5
54 because the formula for the area of triangle is 1/2bh so you just substitute the b and h for 18 and 6
