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.

4 - 7x=39 find the value of x +1
wel
4-7x= 39

Subtract 4 from both sides
-7x= 35

Divide both sides by -7
x= -5

The value of x+1= (-5)+1= -4.

Aleksandr-060686 [28]
The answer is: x = 10, y = 2

Leave a thanks because your welcome :)

Work:

x + y = 12

x - 2y = 6
(10) - 2(2) = 6
10 - 4 = 6
