It's C, the diagonals are not congruent (they aren't equal) and with rectangles they always have to be.

Answer:

Step-by-step explanation:

The diagonals of a rectangle bisect each other and are the same length. The lengths of the diagonals of this figure are ...

AC = √((8-0)² +(6-2)²) = √(64+16) = 4√5

BD = √((5-3)² +(2-6)²) = √(4 +16) = 2√5

The diagonals are different lengths, so the parallelogram is not a rectangle. This is described correctly in choice C:

No, it is not a rectangle because the diagonals are not congruent.

_____

The lengths are found using the distance formula:

d = √((x2 -x1)² +(y2 -y1)²)

Answer:

The result is the same.

Step-by-step explanation:

I think your question is missed of key information, allow me to add in and hope it will fit the original one.

Please have a look at the attached photo.

My answer:

Given the information:

square 12 inches wide
3-inch diameter cookies are cut => its radius is: 1.5 inches

Hence we can find some information:

The area of the square is: $12^{2} = 144$ square inches
The area of a cookies is: $r^{2}$ π = 3.14* $1.5^{2}$ = 7.065 square inches
The total number of 3-inch cookies are: 4*4 =16

=> The total area of the cookies is: 16* 7.065 = 113.04 square inches

=> how much cookie dough is "wasted" when 3-inch cookies are cut:

= The area of the square - The total area of the cookies

= 144 - 113.04 = 30.96 square inches

If the diameter is increased to 4 inches => its radius: 2 inches, we have:

The area of a cookies is: $r^{2}$ π = $2^{2} *3.14 = 12.56$ square inches
The total number of 3-inch cookies are: 3*3 =9

=> The total area of the cookies is: 9* 12.56 = 113.04 square inches

=> how much cookie dough is "wasted" when 4-inch cookies are cut:

= The area of the square - The total area of the cookies

= 144 - 113.04 = 30.96 square inches

The result is the same.

Airida [17]

Answer:
