Help me with this pythagorean theorem please for 20 points.

3 root 7

Step-by-step explanation:

h^2 = b^2 + a^2

12 square = b square + 9 square

144 = b^2 + 81

144-81 = b^2

63 = b^2

b = root of 63

b = root 7 x root 9                         ( since 7x9=63)

b = 3 root 7                                 ( since root of 9 is 3)

PLS mark me as BRAINLIEST

So for the cranberry muffin, for every 12 (a dozen) it's $3
Banana nut muffin: for every 12, it's $4.32
take the $3 and divide it by 12 which is $0.25 for every cranberry muffin
take $4.32 divide by 12 and you get $0.36 for every banana nut muffin
so $0.25 + $0.36 = $0.61
Therefore the answer is B
