Answer:
336 feet²
Step-by-step explanation:
If we have a rectangle that is 30 by 20 feet, that means the area of that rectangle would be 20 × 30 feet squared, which is 600 ft².
If there is a 3 feet sidewalk surrounding it, that means that the end of the sidewalk will extend 3 feet extra around each side of plot. Since there are two ends to one side, that means an extra six feet is added on to each dimension. Therefore, 36 × 26 are the dimensions of the sidewalk+plot. 36 × 26 = 936 ft².
To find the area of the sidewalk itself, we subtract 600 ft² from 936 ft². This gets us with 336 ft².

Answer:
x=4 or x= - 16
Step-by-step explanation:
|x+6|
Now subtract 7 which equals to 3.
|x+6|-7=3
|x+6|=10
Now remove the mode by adding plus minus sign in the front of 10.
x+6=±10
x+6=10 or x+6=-10
x=4 or x=-16
