I am assuming you are supposed to find the area of the shaded rectangle? If so then we must subtract the area of the smaller rectangle from the larger rectangle, so:

(x+9)(x+3) - ((x+1)(x+5))
= x^2 + 12x + 27 - (x^2 + 6x + 5)
= 6x + 22

Two lines, A and B, are represented by the equations given below: Line A: y = x − 6 Line B: y = 3x + 4 Which of the following sh
nadezda [96]

The solution to the system of linear equations is: (−5, −11).

<h3>What is the Solution to the System of Linear Equations?</h3>

The solution to a system is the x and y -coordinates that satisfies the two linear equations.

Given the linear equations:

Line A: y = x − 6

Line B: y = 3x + 4

Now, equating these two equations

x - 6 = 3x + 4

2x = -10

x = -5

y = -11

Hence, the solution is: (−5, −11), because the point satisfies both equations.
