Answer:
9x = 16
Step-by-step explanation:
2+2/3x=3/4

Answer:
18 square centimeters
Step-by-step explanation:
Notice that if e is the midpoint of the side CB, and angle
, then this rectangle is in fact two squares of side 3 cm put together. therefore, side CD has a length of 6 cm, and as a result, the area of the figure is given by the product base times height = 6 x 3 = 18 
The answer is 5. this can be found by creating a factor tree of both numbers
