For this case, we must find the triangle whose value of x is given by 17.
In all three cases, the value of the variable "x" is given by:
Thus, the triangle whose value of x is 17 is triangle 2.
step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
