IrinaVladis [17]

Answer:

28 ft squared

Step-by-step explanation:

The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.

So yeah if someone can help me with
Law Incorporation [45]

Answer:

y = x - 5

Step-by-step explanation:

The equation of the line parallel to the line $ ax + by + c_1 = 0$ is $ ax + by + c_2 = 0 $.

That is, equations of parallel lines differ only by constant.

The given equation is $ y = x + 4 $

This is written as $ x - y + 4 = 0 $

Therefore, the equation of the line parallel to this line is given by $ x - y + c = 0 $

The value of c is determined using the point given.

Substituting the point (3,-2) we get:

$ 3 + 2 + c = 0$

$ \implies c = -5 $

Therefore, the equation of the line becomes y = x - 5.
