The expression is 3|t - y|.
x2 is the same as x times x. In this case x = t+2 so we can say (t+2)2 is (t+2)(t+2) or t2+4t+4
5t - 1 = -11 Therefore, 5t = -10 t = -10/5 t = -2
It normally means 2 times t which can also be expressed as 2t
The expression (3t \times 3t) can be simplified by multiplying the coefficients and the variable separately. First, multiply the coefficients: (3 \times 3 = 9). Then, multiply the variable (t) by itself: (t \times t = t^2). Therefore, the result is (9t^2).
