The area of a trapezoid is:

A = area
a = base 1
b = base 2
h = height
Area = unknown
base 1 = 2.5
base 2 = 7.5
height = 2.5
^^^Plug these numbers into the formula!

A = (10/2)(2.5)
A = (5)(2.5)
A = 12.5
Hope this helped!
Answer: Third option.
Step-by-step explanation:
Some transformations for a function f(x) are shown below:
If
, the function is translated "k" units up
If
, the function is translated "k" units down.
If
, the function is translated "k" units left.
If
, the function is translated "k" units right.
In this case you have the following function:

And you know that the function g(x) is obtained by translating the function f(x) 5 units down and 3 units left; therefore, you can conclude that g(x) is:

Finally, simplifying, you get that this is:

Answer:
x = 3
Step-by-step explanation:
We can solve this by using ratios of similar triangles
3 x
------ = ------------
3+9 12
3 x
------ = ------------
12 12
x must equal 3 to keep the ratios the same
