The formula for how far a moving object travels in terms of the rate, or speed at which it moves, and the travel time, or how long it is moving, is d = rt, where d stands for distance, r stands for rate, and t stands for time. rearrange the quantities in this formula to give a new formula for travel time in terms of distance and rate of travel. a. t=rd b. t=dr c. t=rd d. t=d−r

third option: 6x+8

step-by-step explanation:

we can see that the given question is a sum of series and the values of n vary from 0 to 3

the first term will be:

when n=0, [(0)*x+2] => (0+2) => 2

when n=1, [(1)*x+2] => (x+2) => x+2

when n=2, [(2)*x+2] => 2x+2

when n=4, [(3)*x+2] => 3x+2

so adding up all the terms will give us:

=2+x+2+2x+2+3x+2

=x+2x+3x+2+2+2+2

=6x+8

so,

third option is the correct answer ..

1 is b and 2 is d
