Complete Question:
The area of a trapezium is 400 cm2, the distance between the parallel sides is 16 cm. If one of the parallel sides is 20 cm, then the length of the other side is ______
Answer:
Step-by-step explanation:
Given
--- Area
--- Height
Required
The length of the other side (Side 2)
The area of a trapezium is:
Divide both sides by 8

Answer:
x=13
Step-by-step explanation:
For a to be parallel to b, 7x-26 + 9x-2 would have to = 180.
If we solve this equation,
16x-28=180
16x=208
x=13
x would have to equal 13 for a || b.
Given:
The sequence is 8, 10, 12.5, 15.625,...
To find:
The explicit formula for the given sequence.
Solution:
We have,
8, 10, 12.5, 15.625,...
Here, the first terms is 8.
The common ratio is 1.25. So, the given sequence is a geometric sequence.
The explicit formula for a geometric sequence is:
Where, a is the first term and r is the common ratio.
The explicit formula for the given geometric sequence is:
Therefore, the correct option is A.
