Present area = 120 * 80 = 9600 ft^2 so the new area will be 9600 + 4400 = 14000
So if increase in length = x we have
(x + 120)(x + 80) = 14,000
x^2 + 200x + 9600 - 14000 = 0
x^2 + 200x - 4400 = 0
x = 20 feet answer
The second one is bigger as the square is a even number with the negative whole
It would be 8 + 40 because you multiply the 4 by the 2 and 10
The expression is 55/5 - 20/4
11-5
the answer is 6
