Answer:
7n + 14 and 7(n + 2)
Step-by-step explanation:
We know that since our triangle is isosceles, then two of the sides are the same. Given in the problem, we know that these two congruent sides are both 2n + 7. We also know the third side is 3n.
Perimeter is essentially just the sum of the side lengths of the figure. We simply need to add 2n + 7, 2n + 7, and 3n together:
P = 2n + 7 + 2n + 7 + 3n
Combine like terms:
2n + 2n + 3n + 7 + 7
7n + 14
That's one way we can write it. Another way is to factor out the 7:
7n + 14 = 7(7n/7 + 14/7) = 7(n + 2)
Thus, our two expressions are: 7n + 14 and 7(n + 2).

A.) R(20) = -10(20)^2 + 800(20) = -10(400) + 16000 = -4000 + 16000 = $12,000
R(25) = -10(25)^2 + 800(25) = -10(625) + 20000 = -6250 + 20000 = $13,750
R(30) = -10(30)^2 + 800(30) = -10(900) + 24000 = -9000 + 24000 = $15,000
b.) For maximum revenue, dR/dp = 0
dR/dp = -20p + 800 = 0
20p = 800
p = 40
Therefore, the maximum revenue will be recorded when the price is set at $40.
Answer:
The value of
Step-by-step explanation:
Given : Equation -
To find : Solve the equation?
Solution :
Step 1 - Write the equation
Step 2 - Add 5 both side,
Step 3 - Divide by 3,
Therefore, The value of
The coordinates of the endpoints of the range can be used to calculate the rate of change using the slope formula: m = dy / dx. The coordinates are (pi, -1) and (3pi/2, 2). So, dy = 3pi/2 - pi = pi/2 and dx = 2 - (-1) = 3. Therefore, m = pi/6.
