1.) If a = 24 and b = 45, then c =

c^2 = a^2 + b^2
c^2 = 24^2 + 45^2
c^2 =576 + 2025
c^2 = 2601
c = 51
answer

51

2.) If a = 5 and b = 12, then c =

c^2 = a^2 + b^2
c^2 = 5^2 + 12^2
c^2 =25 + 144
c^2 = 169
c = 13

answer

13

3.) If a = 8 and b = 15, then c =

c^2 = a^2 + b^2
c^2 = 8^2 + 15^2
c^2 =64 + 225
c^2 = 289
c = 17

answer

17

4.) If a = 20 and b = 21, then c =
c^2 = a^2 + b^2
c^2 = 20^2 + 21^2
c^2 =400+ 441
c^2 = 841
c = 29

answer

29

(6,0) i hope it makes enough sense

Hey there,   128 *(2/3) = 85.3

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
