Equivalent ratios are those ratios which are same that is on simplifying each of them, we will get the same answer.
A.
So they are not equivalent
B.
So they are not equivalent
C.
They are not equivalent too.
D.
And they are equivalent. SO the correct option is D .
Answer:
Step-by-step explanation:
Factor it by first setting it equal to 0:
Now subtract 9 from both sides:
Divide both sides by 4:
Then take the square root of both sides:
x = ± , which of course is not allowed. Therefore, we have to allow for the imaginary numbers in this solution. Knowing that,
x = ± is an equivalent radicand, we can now replace -1 with its imaginary counterpart:
x = ±
Each one of the elements in the radicand are perfect squares, so we simplify as follows:
x = ±
And there you go!
