6. Complete the coordinate proof. Given: A(0,6), B(6,6), C(6,0), D(0,0); ZDAB, ZABC, ZBCD, ZCDA are right angles.
Prove: ABCD is a square.
A square on a coordinate plane
Proof:
AB = V(22 – 21)2 + (y2 – yı) so AB =
.
BC
V (x2 – 21)2 + (92 – yı) so BC =
-
.
CD= V(22 – 21) + (92 – yn) so CD=
=
• DA = V(x2 – 21) + (y2 – yı)? so DA=
.
=

the number of the people going.

step-by-step explanation:

the cost to buy one movie ticket is $7. if the total cost for the movie is a function of how many people go, then the input is : the number of the people going.

i dont know the answer but here's a picture of a dog

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363
