i dont know it

step-by-step explanation:

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
