Answer:
C
Step-by-step explanation:
First, factor the original expression:
As we can see, D is the same as above. Eliminate D.
Go through each of the answer choices.
A:
This is equivalent to what we factored. Eliminate A.
B:
This is again equivalent to what we factored. Eliminate B.
C:
This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.
Answer: c
Step-by-step explanation:
because 18 students are going and 10 are staying
Answer:
the diameter is 28 centimeters and the area is 97.4 centimeters
Step-by-step explanation:
the diameter is just the radius plus the radius so its 28
and i just solved for the area and got 97.4
