Well technically this problem is wrong, as two sides are the same on a rectangle on each side.
A. w= -22 so A has a negative solution.
D doesn't have a variable so I'm not sure about it (did you type it correctly?), but because only one side of the equation has a negative number, I'm guessing D is also a negative solution
18 x 4 = 72
(9 x 2) x 4 = 72
9 x (2 x 4) = 72
Answer:
(4+√142)/(3) or x=(4-√142) /3
Step-by-step explanation:
(4+√142)/(3) or x=4-√142 /3
