<h3>Answer :</h3>
There are two statements here, showing quantities in real world which are additive inverse of each other :
2. Noa hiked 2 mi up a mountain trail and then hiked 2 mi down the trail.
here, we can depict going up as +2 miles and going down the trail as -2
4. A hot-air balloon ascends 2000 ft from the ground and then descends 2000 ft.
And here we can assume going up the ground aa + 2000 ft and going down aa - 2000 ft .
Answer:
x= -1 , i(sqrt11) , -i(sqrt11)
Step-by-step explanation:
subtract 11x from both sides
-x^3 - x^2 - 11x = 11
subtract 11 from both sides
-x^3 - x^2 - 11x - 11 = 0
Factor the left side of the equation
- (x - 1)(x^2 + 11) = 0
Set both factors to zero and solve for x
x + 1 = 0 x^2 + 11 = 0
-1 -11
x^2 = -11
x = -1 x = +/- i(sqrt11)
Answer:
So the price of house 0f house after n number of year = 380,200 - 11800n
Step-by-step explanation:
Bob has a bought a new house for $380,200. He estimates the value of the house after each year and he also assumes that the value of the house decreases by the same amount each year.
So to find the equation to define the value of the house after each year, we have to find out how much depreciation happens for the value of the house in each year.
Final value = $321,200
Depreciation each year = 
= $11,800
So the price of house 0f house after n number of year = 380,200 - 11800n
Here is your answer:
4x² + 28x + 49
4x² + 14x + 14x + 49
2x(2x) + 2x(7) + 7(2x) + 7(7)
2x(2x + 7) + 7(2x + 7)
(2x + 7)(2x + 7)
(2x + 7)²
= 28
Hope this helps!
