Answer:
The solution is:
Step-by-step explanation:
Given the expression
Solving
so
∵ 
Therefore, the solution is:
Answer:
x = 6
Step-by-step explanation:
Assuming the figure is a parallelogram then opposite sides are congruent, thus
3x - 6 = 12 ( add 6 to both sides )
3x = 18 ( divide both sides by 3 )
x = 6
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
<h3>What is an
equation? </h3>
An equation is an expression that shows the relationship between two or more numbers and variables. An independent variable is a variable that does not depend on other variables while a dependent variable is a variable that depends on other variables.
Profit is the difference between revenue and cost. Given that:
R(r) = 2r⁴ - 3r³ + 2r - 1 and C(r) = r⁴ - r² + 2r + 3
P(r) = R(r) - C(r)
P(r) = (2r⁴ - 3r³ + 2r - 1) - (r⁴ - r² + 2r + 3) = r⁴ - 3r³ - r² - 4
The expression that represent the profit is given by P(r) = r⁴ - 3r³ - r² - 4
