The diagonals of quadrilateral EFGH intersect at D(?3,4). EFGH has vertices at E(3,7) and F(?4,5). What must be the coordinates

Katen [24]

Answer:

G(3, 1), H(2, 3)

Step-by-step explanation:

When D is the midpoint of EG, it means ...

D = (E + G)/2

G = 2D -E = 2(3,4) -(3,7) = (2·3-3, 2·4-7) = (3, 1)

Likewise, H is ...

H = 2D -F = 2(3,4) -(4,5) = (2·3-4, 2·4-5) = (2, 3)

pishuonlain [190]

Answer:

$84\text{ in}^2$ .

Step-by-step explanation:

We have been given that Mrs. Chen's students are making and decorating gift boxes for a nursing home. The boxes are 7 inches wide, 7 inches long, and 7 inches high. We are asked to find the amount of cardboard that is needed for each box.

We will use surface area of cuboid formula to solve our given problem.

$SA=2(lw+lh+hw)$ , where,

l = Length,

w = Width,

h = Height

$SA=2(7\text{ in}\cdot7\text{ in} +7\text{ in}\cdot7\text{ in}+7\text{ in}\cdot7\text{ in})$

$SA=2(14\text{ in}^2+14\text{ in}^2+14\text{ in}^2)$

$SA=2(42\text{ in}^2)$

$SA=84\text{ in}^2$

Therefore, Mrs Chen needs 84 square inches of cardboard.
