Answer:
A= 8
B= -5
C= -14
Step-by-step explanation:
Area of Rectangle = length * width
Area of the shaded Rectangle:
Area = l * w
Area= (4x + 1) (3x - 5)
Open the brackets
A= 12x^2 - 20x + 3x - 5
A = 12x^2 - 17x - 5
Area of the Unshaded:
The Unshaded portion is a square. Hence, it's area = l^ 2
Area = (2x - 3) ( 2x - 3)
A= 4x^2 - 6x - 6x + 9
A= 4x^2 - 12x + 9
To get the exact shaded portion
A(Shaded) = (12x^2 - 17x - 5) - ( 4x^2 - 12x + 9)
Area = 8x^2 - 5x - 14
A= 8
B= -5
C= -14
Answer:
-52

Answer:
P(x) = 35,900 + 2,800(x-1)
Step-by-step explanation:
P(x)
P(1) = $35,900
P(4) = $44,300
Difference in profits
P(4) - P(1)
= P(3)
= $44,300 - $35,900
= $8,400
Rate of change per year = $8,400 / 3
= $2,800 per year
The linear equation
P(x) = 35,900 + 2,800(x-1)
Where
x = number of years
Usually, you're asked to model a situation with an equation. Here, you're given the equation and asked what situation it models.
The features of the equation that are of interest are ...
- multiplication of the unknown value by 17.35
- comparison of that product to 624.60, expecting the product to be greater than that value
The first two offered scenarios involve addition of an unknown value, not multiplication.
The third offered scenario compares a purchase price to a budget amount. Answering a question like this involves a "less than" comparison, not a "greater than" comparison.
The last offered scenario involves finding a variable value that will result in the product 17.35x exceeding 624.60—exactly what the given inequality models.
The appropriate choice is ...
