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= 
Answer:
given
n=9
a=1
d=3-1=2
Step-by-step explanation:
now , by formula,
sn = n/2(2a+(n-1)d)
= 9/2(2×1+(9-1)×2)
=9/2×18
=81
Answer:
the answer is B
Step-by-step explanation:
Just estimate ex: 5 x 5 would be 25, so sqrt 22 would be just before the 5.
I think it is x > 5 because if you combine like terms you would get 2x-4>6 then you add 4 To 6 which is 10 then you do 10÷2 which is 5
