Answer:
22 degrees
Step-by-step explanation:
3,4,6,7,9. It’s the last answer choice
for one show it will be 23.1 minutes if you multiply 2.30 minutes by 3 and get 6.9 you subtract 6.9 from the 30 minutes and you should 23.1 minutes
The value of x is 
Step-by-step explanation:
Given:

Rearranging the radical on left side,

Power on both sides,

Simplifying the left,

For the RHS equation, use the property of (a-b)² = (a²-2ab+b²),

Now calculating its powers,

Now sending -4√x to the LHS (left side), its sign becomes plus (+),

Now the +x and -x will be cancelled,


Bringing 4 to the right side, it becomes the denominator,


Now powering both sides,
