Answer 3

distance formula

Answer 4

\(\sqrt{(x2-x1)^2 + (y2-y1)^2}\)

Answer 5

(2, 10) and (18, -18)
x1 y1 x2 y2

Answer 6

plugin

Answer 7

So (18 - 2)^2 + (-18 - 10)^2

Answer 8

sqrt of that

Answer 9

Do I simplify it, and then sqrt it?

Answer 10

yes. first simplify, then sqrt

Answer 11

(16)^2 + (-28)^2 = 256 + 784 = 1040 = 32.2490309932

Answer 12

So 32.35 ?

Answer 13

32.25*

Answer 14

yes! gw

Answer 16

ohk.. oly if its not long, else we can do tomoro...

Answer 17

A (4, 4), B (7, 0), C (11, 3), and D (8, 7) are four points on the coordinate grid. Miranda and Pete joined the points using straight lines to draw a quadrilateral ABCD.

Which statement is correct?

Pete is correct because all the four sides of the quadrilateral ABCD are equal, therefore it is a rhombus.

Miranda is incorrect because she has used incorrect formula to calculate the slope of the lines.

Pete is incorrect because he has used incorrect formula to find the distance between the points of the segments.

Miranda is correct because the slope of AB is equal to DC and slope of BC is equal to AD, therefore it’s a rhombus.

Answer 19

after proving its a parallelogram - to prove it is not a rhombus, you need to prove adjacent sides are not equal. but Mirinda didnt do that - So he is incorrect.

Answer 20

this is the answer :-

Pete is correct because all the four sides of the quadrilateral ABCD are equal, therefore it is a rhombus.
