(m^2- 4n)(m^4+4m^2n+16n^2)
Answer:
(3, 5)
Step-by-step explanation:
It would be (3, 5) because since Juans house is in the same quadrant as the school there wouldn't be any negative numbers in the coordinates. The only coordinate that doesn't have negative numbers is (3, 5). That's your answer.
Answer:
The wide of the walkway is 5ft.
Step-by-step explanation:
In first place you have a rectangular garden of 30ft by 40 ft as shown in Figure 1 (Added file).
So, the area of this rectangle is:

Area=1200ft
Now, the new garden has a walkway of uniform width around it, and the area of the new rectangle is one-half the area of the old garden

In order to be a walkway of uniform width it's necessary to substract of each side the same amount, for this case will be 5 ft, as shown in the Figure 2. Now the new rectangule is 20ft by 30ft.

Which is exactly one-half the area of the old garden.
This means the width of the walkway is 5ft.
