3/8 = 0,375
0,375 * 100% = 37,5 %
To find the other factor you just divide the first factor by the area and you get (x-6)
And you can check by multiplying both the factors by each other.
(X+8)(X-6)
x^2+2x-48
Brainliest my answer if it helps you out?
77% because if you add 20% to 3% you get 23% total and 100%-23%=77%.
