N is an odd number.

Answer:

True:

Step-by-step explanation:

First, you should know that the square of any odd number is also odd.

The easiest way to go about this is to plug in an odd number for n. Lets use 3:

Plug 3 into A:

$3^{2} -1=9-1=8$

Plug 3 into B:

$3(3-1)=9-3 = 6$

Plug 3 into C:

$(3-2)^{2} = 2^{2} = 4$

Plug 3 into D:

$3^{2} +2 = 9+2=11$

Plug 3 into E:

$3(3-2) = 9-6 = 3$

Plug 3 into F:

$(3-2)^{2}=1^{2} =1$

Anita is making a curtain to surround a table. She bought 3 1/4 yards of fabric. Her total cost was $13. What was the cost per y

Ratling [72]

3.25y=13. Isolate y by dividing both sides of the equation by 3.25. So 3.25y/3.25=13/3.25. Your answer is therefore 13/3.25, or 4
