Answer:

Then the coordinate of point C is (4,3), and the coordinate of point D is (-4,3).

Step-by-step explanation:

Given that,

                The upper-left coordinate on a rectangle is (-4,4).

                The upper-right coordinate on a rectangle is (4,4).

                Area of rectangle is 8 square unit.

Let, ABCD is a rectangle.

The coordinate of point A is (-4,4) and the coordinate of point B is (4,4).

Diagram of rectangle ABCD is shown below:

Now,

AB= \sqrt{(4+4)^{2}+(4-4)^{2}  }

      =\sqrt{(64+0)}

      =\sqrt{64}

      = 8\  unit

∵Area of rectangle = Length \times Breadth

8 square unit = 8\ unit \times Breadth

∴ Breadth =1\ unit

BC=\sqrt{(4-4)^{2}+(y-4)^{2}  }

      =\sqrt{(y-4)^{2}  }

⇒ 1=\sqrt{(y-4)^{2}  }

squaring both sides, we get

⇒ 1=(y-4)^{2}

⇒ (y-4) = ±1

∴y=3

Then the coordinate of point C is (4,3), and the coordinate of point D is (-4,3).

Sewing patterns recommended buying extra fabric in case of mistakes. Darlene bought 7 yards of fabric, plus 20% extra fabric. Ch
Debora [2.8K]

Answer:

Darlene bought more fabric

Darlene bought 3.4 yards more

Step-by-step explanation:

Darlene = 7 yards + 20% extra

= 7 yards + (20% of 7 yards)

= 7 + (20% × 7)

= 7 + (0.2 × 7)

= 7 + 1.4

= 8.4 yards

Chris = 4 yards + 25% of 4 yards

= 4 yards + (25% of 4 yards)

= 4 + (25% × 4)

= 4 + (0.25 × 4)

= 4 + 1

= 5 yards

Darlene bought more fabric

How much more?

Darlene - Chris

= 8.4 yards - 5 yards

= 3.4 yards

Darlene bought 3.4 yards more
