Answer:

24

Step-by-step explanation:

The algebraic expression is:

2ac + 3bc - abc

a = 2, b = 2, c = 4

2ac + 3bc - abc = 2(2)(4) + 3(2)(4) - (2)(2)(4) = 16 + 24 - 16 = 24

Dmitrij [34]

Answer:

{3,-1}

Step-by-step explanation:

Iodine-125 has a half-life of about 60 days. How many milligrams of a 1000 mg sample will remain after 240 days?
Tomtit [17]

240 days is 4 times the half-life, which means that a sample of 1000 mg will decay to

\dfrac{1000}{2^4}=\dfrac{125}2=62.5\,\mathrm{mg}

after 240 days.
