Answer: Nothing multiplies to 40 and adds to -6, it is impossible
7m would be the length to the missing side. Hope I helped
Cross multiply
(3x - 1)(4x + 5) = (2x + 6)(6x - 4)
12x^2 + 11x - 5 = 12x^2 + 28x -24
Solve for x
-17x = -19
x = 19/17
The answer is 16000000000.
Because you take the decimal and move it 10 times to the right.
