Use the formula a^2 - b^2 = (a -b)(a + b). So: t^2 - (t - 1)^2 = [t - (t -1)][t + (t -1)] Now you can work and simplify the given expression. =(t - t +1)(t + t -1) =(1)(2t -1) = 2t -1
The answer to the question "3T in a T" is "3 Trillion in a Terabyte." In digital storage nomenclature, a terabyte (TB) is a unit of information equal to approximately 1 trillion bytes. Therefore, 3T in a T signifies 3 trillion bytes in a terabyte.

T+(3-2t)=4t+1. Assuming the two T's , T and t are the same variable, lets proceed. t+(3-2t)=4t+1 3-t=4t+1 2-t=4t 2=5t last step is yours
