Toni Mahoney is using Biscuit Betty's recipe that requires 5 1/3 pounds of flour to make biscuits for her brunch. Suddenly, Toni
learns that 4 times as many people are coming to her bunch than originally planned. How much flour will Toni need to make her biscuits? Explain how tou got your answer.
21 1/3 pounds of flour. We know it takes 5 1/3 pounds of flour for one brunch. So, if there are 4 times as many people, we have to multiply 5 1/3 by 4. After you do 5 1/3 times 4 you will get 21 1/3 pounds of flour.
The pattern is: ( a - b )² = a² - 2 a b + b² ( square of last term of binomial - the missing term) x² - 2 · 8 · x + 8² = x² - 16 x + 64 = ( x - 8 )² The missing term is: 64
