Answer:
Area of the Trapezoid is= 
Step-by-step explanation:
The given figure is in the shape of a trapezoid:
Area of a trapezoid= (1/2)*(Sum of parallel opposite sides)* (Distance between the parallel sides)
The parallel sides are: 6 cm and 3 cm
Distance between parallel sides= 3 cm
Area:

Area of the Trapezoid is= 
Ali's solution is incorrect
same as 9y + 1y
10y
x^3-10x^2=27x-18=0 has no solutions
x^3-10x^2-27x-18=0 has 3 solutions
x^3-10x^2-27x-18=0 also has three solutions
