Answer:
180 cm2 is the answer you can multiply all sides
C. X=9
First, you distribute the 6 to the x-3. You get 6x-18=3x+9 from that. Then, you add 18 on both sides giving you 6x=3x+27. After that, you subtract 3x on both sides giving you 3x=27. Last, you divide 3 on both sides giving you the final answer of x=9
You would place a #line going from negatives on left to positive on right then place a point at positive 5 and go back 5, 3 times
A. directly proportional 1/x = 1/y
