....
Answer:

Step-by-step explanation:
To solve, we need to take square root of both sides first:

Now we use the property of radical shown below to simplify square root of 28:
Property: 
Now, we have:

Now we take 4 to the other side and isolate x:

first answer choice is right.
Notice that the denominator is a multiplied by 2 for each fraction.
1/1•2 = 1/2
1 /2•2 = 1/4
1/4•2 = 1/8
1/8•2 = 1/16
1/16•2 =1/32
The next size is 1/32.
Answer:
A and B are functions
Step-by-step explanation:
for A, none of the x's repeat which makes it a FUNCTION
for B, when it starts with x^2, it will always be a FUNCTION (its a quadratic)
for C, 10 repeats for the x so it is NOT A FUNCTION
1200 ÷ 4 = 300
