(4,18); (6,22); (8,26)

Step-by-step explanation:

Plug in the numbers 4, 6, and 8, in for d using the equation.

c=2d+10

c=2(4)+10

c=8+10

c=18

(4,18)

c=2d+10

c=2(6)+10

c=12+10

c=22

(6,22)

c=2d+10

c=2(8)+10

c=16+10

c=26

(8,26)

14

18

22

26

Step-by-step explanation:

c = 2d + 10

1st one: substitute 2 for d

c = 2 x 2 + 10

c = 14

2nd one: substitute 4 for d

c = 2 x 4 + 10

c = 18

3rd one: substitute 6 for d

c = 2 x 6 + 10

c = 22

4th one: substitute 8 for d

c = 2 x 8 + 10

c = 26

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
