Answer:
He set the factored expressions equal to each other. instead of setting them equal to zero
Step-by-step explanation:
f(x) = x^2 + 4x + 3. His work is shown below.
0 = x^2 + 4x + 3
0 = (x + 3)(x + 1)
Here is where we use the zero product property
x+3 = 0 x+1 =0 We do not set them equal to each other

Answer:
$857 billion
Step-by-step explanation:
Since 2006, the amount of money spent at restaurants in a certain country has increased at a rate of 5% each year. In 2006, about $580 billion was spent at restaurants.
2014-2006=8 so 2014 is 8 years from 2006
If the trend continues, the amount of money spent at restaurant in 2014 will be (1.05)^8 times that of the amount in 2006:
$580*(1.05)^8 = $856.9
About <u>$857</u> billion will be spent at restaurants in 2014 if the trend continues.
