That depends on where you saw it. If you saw it on a piece of clothing, it means the piece of clothing is for a 2 year old toddler size. If it was on a recipe, it means two tablespoons.
It normally means 2 times t which can also be expressed as 2t
The geometric mean of n numbers (t{1}, t{2}, ..., t{n}) is given by (Π t{n})^(1/n) → geometric mean of 8.5 and 12.4 = (8.5 × 12.4)^(1/2) = 10.26645... ≈ 10.266
Tale of 2 Cities
2 s means 2 times s and t b means t times b 2 seats on a tandem bicycle
2 x b x t x a x c to the power 2
Do you mean f(t) = -16t^2 - 48t + 160? This is a function, which can't be "solved" as it is. - you could factor it: -16(t + 5)(t - 2) - you solve for f(t) = 0: t = 2, -5
If you mean t^2 +11t +10 then it is (t+10)(t+1) when factorized
Residential two family
Two turtle doves and a partridge in a pear tree
2 heads are better than one
If you mean: 6t -2 = 28 then the value of t is 5
T squared is T times T. T squared and T squared appears to be the addition of T squared with itself. That answer would be 2T squared or 2T^2
