Answer:La media aritmética es la suma de todos los datos dividida entre el número total de datos :)
Answer: Option (D) Add the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.
Explanation:
Given expression:

<em>Step-1: </em>Add the exponents and keep the same base by using
property.

Step-2: The reciprocal of
is
, which is 
Step-3: The exponent of
is +1; therefore, change the sign of exponent. The end expression will now become:

Hence, the correct option is (D) Add the exponents and keep the same base. Then find the reciprocal and change the sign of the exponent.
Since the equations for area is A= L*W
A= 9*4= 54
You can factor out a 2 from all. Idk if that helps but here ya go. 10x+3x-4
Answer:
yes because -3x4 would be negative 3 four times, reseulting in a negative number
Step-by-step explanation:
hope this helped
