In the United States, a person eats more than 40,000 pounds of bread in a lifetime if she or he lives to be 80 years old. Does t
Shalnov [3]
Look at some shorter periods of time to decide whether their reasonable. Do that by simplifying the fraction. . . . . 40,000 pounds / 80 years = 4,000 pounds / 8 years = 2,000 pounds (1 ton) / 4 years = 1,000 pounds / 2 years (have you decided yet ? Well, simplify it some more) 1,000 pounds / 2 years = 500 pounds per year = almost 1 and 1/2 pounds of bread every day of your life. NOW what do you think ? Make sense ?

(6+√-64)(3-√-16) Multiply. This is urgent, please explain this to me!
romanna [79]

Answer:

50

Step-by-step explanation:

\sqrt{-64} and \sqrt{-16} can be expressed in complex form, with \sqrt{-1} = i

\sqrt{-64} = \sqrt{64(-1)} = \sqrt{64} × \sqrt{-1} = 8i

\sqrt{-16} = \sqrt{16(-1)} = \sqrt{16} × \sqrt{-1} = 4i

the factors can then be expressed as

(6 + 8i)(3 - 4i) ← expand using FOIL

= 18 - 24i + 24i - 32i² [ i² = (\sqrt{-1} )² = - 1 ]

= 18 - 24i + 24i + 32 ← collect like terms

= 18 + 32 + 0

= 50
