Answer:
The length of the rectangle is given as:
(9x + 6)
Step-by-step explanation:
The area of a rectangle is given as:
Length × Width
Area of the rectangle = 45x² − 42x − 48
Width = 5x - 8
We solve for the length of the rectangle by factorising the area of the rectangle
45x² − 42x − 48
45x² - 72x + 30x - 48
(45x² - 72x )+ (30x - 48)
9x(5x - 8) + 6(5x - 8)
(5x - 8)(9x + 6)
Therefore:
The length of the rectangle is given as:
(9x + 6)

Answer: $34.78
Step-by-step explanation:
<span>For the answer to the question above, according to Weber's law, the perceptible differences are proportional to the initial perception. So, with just a 10% increase in area was perceptible, but an increase of 1-9% in the area is considered imperceptible. The 9% increase in area reflected by 200 to 218 would be perceived as the same size as before.
The <u><em>answer is 218</em></u></span>
Answer:
90
Step-by-step explanation:
1. Start by making functions for the numbers
2. You can plug in these functions into a graph to figure out the x variable
- The intersection point of the two lines reveals the x and y
- The x would be your answer
3. To check if your x is right, plug it back into the two equations
- .89(90)+36=116.1
- 1.29(90)=116.1
