Plz help i will mark brainiest

its b

Step-by-step explanation:

Rearrange the Pythagorean Theorem to find the missing side. The Pythagorean Theorem is:

c2=a2+b2

where c is the hypotenuse and a and b are the sides.

√(26^2- 24^2) = 10

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
