I am using a T1-83 calculator and working out the problems on Page 28, but cannot get the right answers for 2, 6, 7 and 8. It must be that I am plugging in the figures incorrectly. Can anybody out there help? The different stages would help. Thanks.

A = B

A^2 = (A)(B)

A^2 - B^2 = AB - B^2

(A - B) (A + B)= B(A - B)

A + B = B

B + B = B

2B = B

2 = 1

I just want to see how many people figure it out because it took me a while to get it

i heard that if the energy in an object increases, so does its mass. Thus it is impossible to accelerate an object to the speed of light because due to the extreme kinetic energy, the mass is close to infinity. is this true or is there a different hypothesis to this?
