The sign of each Y coordinate changed
Sqrt55. Use the pythagorean theorem; 3^2 + x^2 = 8^2
<u>Answer:</u> Yes, I can.
Although you haven't asked for the solution, here it is anyway:
2^x = e^(x+2)
x ln(2) = x+2
x ln(2) - x = 2
x [ ln(2) - 1 ] = 2
x = 2 / [ ln(2) - 1 ]
x = 2 / -0.3069... =<u> - 6.518</u>... (rounded)
