Answer:
We have
k^2 - 25f^2 + 5kf - 25f^2 =
k^2 - (5f)^2 + 5f( k - 5f) =
( k - 5f )( k + 5f ) + 5f( k - 5f ) =
( k - 5f )( k + 5f + 5f ) =
( k - 5f )( k + 10f );
Step-by-step explanation:
Answer:
x-intercept means the advertising expense when the company's profit was zero dollars ⇒ D
Step-by-step explanation:
Let us solve the question
∵ P = -250x³ + 1,505x² - 300, for 0 < x < 6
∵ P is the profit in tens of thousands of dollars
∵ x is the advertising expense in tens of thousands of dollars
∴ x is the independent variable
∴ P is the dependent variable
→ x-intercept means value x when P is 0
∵ The x-intercept is the value x at P = 0
∴ x-intercept means the advertising expense when the company's
profit was zero dollars
A because 2(5) is 10 + 4(3) is 12 which makes 22 and 6(5) is 30 + 2(3)=6 which makes 36. Finally, both are now true with that ordered pair making it the answer.
