PEMDAS
doing the stuff in the parenthesis first
71.1 - 2.27 x (2)4
then multiply left to right
71.1 - 4.54*4
71.1 - 18.16
52.94
therefore 52.94 should be your answer
Answer:
m angle CDE is 163 degree
Step-by-step explanation:
98+65=163
Answer: 60° is the right answer
Step-by-step explanation:
First of all, 2^n and 3^n are exponentials with different bases, and thus their sum cannot be simplified beyond 2^n + 3^n. In other words, these two functions cannot be combined ino one function (such as 4^n).
You may gain much more insight by graphing 2^n, 3^n and 4^n to determine whether there is truth in the given statement or not.
Answer:
The equivalent expressions are:
Step-by-step explanation:
Given equation for finding area of a trapezoid:
where 
represents area, 
represents height and 
represents the base lengths of the trapezoid.
Evaluating by rearranging the equation to find an equivalent equation.
Multiplying both sides by 2.
Dividing both sides by
