The correct answer is letter d.
The reason is because of what each of these statements represent in math.
A number directly outside of a. parentheses means that we have that many groups of everything inside of the parentheses.
9(y + 3) means we have 9 groups of y and 9 groups of 3. This is the same as saying 9y + 27 or 27 + 9y.

Step-by-step explanation:
because on the chart is says 19% under burgers for teachers.
Tell me if it is right.
Let the variable of the equation be x.
Solution of the equation is given to us, hence,
x = -3 and x = 9
x + 3 = 0 and x - 9 = 0
Multiplying,
(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27
Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
Answer:
The population reaches 42,336 fish in 2258
Step-by-step explanation:
<u>Given</u><u>:</u>
<u>To Find:</u>
Time taken to reach 42,336 = ?
<u>Solution:</u>
According to the question x is the number of years after which the population .
Then
= 0
Solving using quadratic formula
x=261.337 x=−261.268
Neglecting the negative value we get
x = 261.337
x = 261 approx
261 years after 1997 = 2258
