will compute the number of glasses of tea Fiona can serve based on the number of cups used for lemonade.
0 ounces, when you split between four people there are 8 Oz in each cup, therefore he drank the whole cup.
Pam has more because 34*8=204 and if Louis had 202 than 204 is greater than 202 :)
Answer:
ab = 144
Step-by-step explanation:
Assuming you mean a² + b² = 612, then
(a + b)² = a² + 2ab + b² , that is
30² = a² + 2ab + b² , so
a² + 2ab + b² = 900
a² + b² + 2ab = 900 ← substitute a² + b² = 612
612 + 2ab = 900 ( subtract 612 from both sides )
2ab = 288 ( divide both sides by 2 )
ab = 144
