Answer:

CD=2\\\\BD=8

Step-by-step explanation:

A (4, 7), B (6, 7), C (4, -1), and D (6, -1)

Using Distance formula:

CD:

              \sqrt{(6-4)^2+(-1-(-1))^2} \\\\=\sqrt{(6-4)^2+(-1+1)^2} \\\\=\sqrt{2^2+0}\\\\=\sqrt{4}\\\\ =2

BD:

          \sqrt{(6-6)^2+(-1-7)^2} \\\\=\sqrt{0+(-8)^2}\\\\=\sqrt{64} \\\\=8

CD=2\\\\BD=8

Three consecutive odd integers are such that the sum of the first and second is 31 less than 3 times the third. Find the integer
Otrada [13]

1st:x

2nd x+2

3rd: x+4

(x)+(x+2) = 3(x+4)-31

distribute

2x+2 = 3x+12-31

2x+2 =3x-19

subtract 2x from each side

2 = x-19

add 19 to each side

21 =x
