Answer:
Step-by-step explanation:
9 + 4x = 52
4x = 43
x = 10.75
4(10.75) = 43
Answer:
-2
Step-by-step explanation:
You first get the sqrt for everything.
64-25•2
------------
3-10
Then multiply the 25 and 2 first because of PEMDAS.
So
64-50
---------
3-10
Then subtract from both top and bottom.
14/-7
Then divide.
-2
Hope this helps
Brainliest would be appreciated.
All real values of x except x = 2
Hope i did it right^^
Answer:cos theta = -(1)/2; tan theta = sqrt(3)
cos theta = -(1)/2; tan theta = -1
cos theta = (sqrt(3))/4; tan theta = -2
cos theta = 1/2; tan theta = sqrt(3)
cos theta = 4/3
