Try D
Step-by-step explanation:
Answer:
The ideal mechanical advantage (IMA) is
.
Step-by-step explanation:
The ideal mechanical advantage is the ratio of length of longer lever
to that of shorter lever
IMA 
Please refer to the image attached.
We could see that the the resistance load moves
cm towards the fulcrum so the distance of resistance load from fulcrum 
Now the as the effort force moves
towards the fulcrum overall distance from the fulcrum to the effort force (load) 
Plugging the values of the distances in IMA formula we can have.
IMA
.
So the IMA of the fulcrum (simple machine) 
Answer:
The first one
Step-by-step explanation:
In this question, we are trying to find X, so can solve this by back-solving. multiply the choices by the A until they equal B. If you do it for the first one then you should gett B.
Answer: ±√2
Step-by-step explanation: A fraction is undefined when its denominator is =0 or undefined. so we need to get 2/3x²-6=0 or undefined. so we can also do 3x^2-6=0. Solving yields ±√2!
Y=x+7 all you have to do is simple algebra and add x to get y by itself and divide 14 by 2
