Area of a trapezoid = a+b+c x h
10 + 5 +12 = 27 x h
27h = 27 x 1.5 = 40.5
Answer: 
Step-by-step explanation:
Given
For figure (i) both triangles are congruent


For figure (ii)
Two triangles WXZ and WZY are congruent

The answer is C. -<span>3 3/4, -2 1/4, 1 1/8
It is because the highest number in the negatives, -3 3/4, is always the lowest. Obviously if there is no negative sign it is positive. 1 1/8 is the only positive so it is the greatest. And -2 1/4 is lower that -3 3/4. So it is higher than -3 3/4 but lower than 1 1/8.
I'm sorry I'm not the best explainer, but does this help?</span>
Answer:
C. 
Step-by-step explanation:
Iterative geometric sequence:

Recursive geometric sequence:

The equations are very similar and you only really need to rearrange it. The factor (2/3) and the first term (9) are given, so you can write the iterative equation:

And so the answer is C.
The answer for this question would be 10
