The answer is 5:2 ration, it's already fully simplified
The second one is a function/Option B. In a function the x values must be different. If the x values are the same you can conclude that the relation is not a function.
Answer:
Expression for area = 3x² - 15x - 42
Step-by-step explanation:
Given that:
Length of rectangle desktop = 3(x+2) = 3x+6 units
Width of rectangle desktop = x - 7
Area of rectangle desktop = Length * Width
Area of desktop = (3x+6)(x-7)
Area = 3x(x-7) +6(x-7)
Area = 3x² - 21x + 6x - 42
Area = 3x² - 15x - 42
Hence,
Expression for area = 3x² - 15x - 42
The range is B in this case if it ask for domain it’s A
This is little bit confusing because its a rectangle. I would assume that the equation is 3x=180, but that depends on how long the rectangle is.
Hope this Helps u!
