Answer:
the answer is C . π×(92)2
Step-by-step explanation .
Not A because:
(Subtract 11 from both sides)
4n > -20
(Divide both sides by 4)
n > -5
Because we have found that dividing the negative number by 4 does not work, we know B is also wrong.
Not C because:
(Subtract 11 from both sides)
-4n < -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n > 5
So, it must be D!
Here's why:
(Subtract 11 from both sides)
-4n > -20
(Divide each side by -4)
(Reverse inequality sign because you are dividing by a negative number)
n < 5
Hope this helps!
But i really need a name of this book and authors :)
