It is actualy A = w * l
so
A = 264
then we minus 30 which equals both areas of the triangles combined, so the final answer is...... 234

Step-by-step explanation:
B) x>-3
Three and eight hundredth seventy two thousandth
First step: (simplify) y+9+7y+63, Second step: (combine) 8y+72
If you would have to graph x=7, you probably know that this is a vertical line at, well, x=7.
| x | = 7 is nothing more than two vertical lines, namely x=7 or x=-7, as you already wrote down.
| x | = -8 has no (real) solutions, so there is nothing to graph.
