Which is the value of the expression 2t+12 when t=1.2?

14.4

Step-by-step explanation:

To evaluate a variable expression means to find the value of the expression when the variable is (or variables are) ... 3(4)−2(5)=12−10=2 ... If there is only one variable in an expression, we don't always need to mention it: ... What is the variable expression for (2t+4)3+6(-5t)-(-8)? ... How do you evaluate 1.2g if g=77?

(a) the volume of the cone is 20/3 in3

hence, option a is correct.
