6m and 15m have a GCF of 3m, so divide both of them by 3m to simplify the fraction.

( 4 / 5 )^-2 = ( 5 / 4 )^2 = 25 / 16 ;
Answer:

Step-by-step explanation:
The area of a trapezoid can be found by multiplying the average of its bases and its height.
We're given:
- One base of 4 cm
- One base of 12 cm
- Height of 1/6 cm
To find the average of a set of
values, add all the values in the set and divide by
. Therefore, to find the average of the two bases, we add 4 to 12 and divide by 2.
The average of the bases is therefore 
Thus, the area of the trapezoid is

After substituting in what the symbols are really supposed to be it looks like this: 19-33/11+5*20. Use PEMDAS and plug it in to a calculator
NO parenthesis
NO exponents
Multiplication: 5*20=100
19-33/11+100
Division: -33/11= -3
19-3+100
Addition: -3+100= 97
19+97
