We must remember the equation to find the area of a trapezoid first.
Area =

A and B are the bases (6 and 12)
The height is 6 for each trapezoid
Now Solve!
====================================================================
SOLVING...
Area =

Area =

Area = 9 * 6
Area = 54
Since there are two trapezoids, multiply 54 by 2
54 x 2 = 108
Area = 108
Answer:

Step-by-step explanation:
Given
--- rate


Required
Determine which solution is correct or incorrect
The solutions are not given. So, I will provide a general explanation
The amount (n) is calculated as:

So, we have:


The above is the general equation to solve for the amount, given h hours
When h = 2.5, we have:


Answer:
Step-by-step explanation:
Perform the indicated multiplication first:
25000 - 500bx + 50ax - abx²
It would seem that this should be part of an equation, and that the other part is missing; without another part, there's no way to determine the values of a and b. Please ensure you have copied this problem down completely.
