A= (a+b+c)h is the formula. I hope this is helpful for you. I am pretty positive it will help.
Answer:
The answer to the equation is 16
Answer:
x = pi, 3pi, 5pi etc
x = -pi, -3pi, -5pi etc
Step-by-step explanation:
cos^2 x + 2 cos x + 1 = 0
replace cos x with m
m^2 + 2m +1 = 0
solve by factoring (this is a^2 +2ab+b^2 = (a+b)^2 where a =m and b=1)
(m+1)^2=0
take the square root of each side
m+1 =0
m=-1
now replace m with cos x
cos x = -1
take arccos of each side
arccos cos x = arccos (-1)
x = pi, 3pi, 5pi etc
Answer:
The answer is x = -17/6.
Step-by-step explanation:
Given:
5 1/3 + x = 2 1/2 . Using least common denominator.
Now, to solve the equation:


Subtracting both sides from 16/3 we get:

Now, the least common denominator of 2 and 3 is 6.
So, we using this we calculate:


Therefore, the answer is x = -17/6.
The conclusion that is valid based on the result of the test would be : A. Her students on average, do not take 30 minutes on the quiz, contrary to what the textbook company stated
we can see in the statement that the average student only need about 25 minutes to take the quiz
hope this helps
