Jenna has already cycled 8 kilometers this year, plus she plans to cycle 2 kilometers during each trip to work. Write an equation that shows the relationship between the number of trips to work t and the total distance cycled d.

Step-by-step explanation:

Given

Required

Determine the expression for this scenario

The expression can be derived from:

Substitute d for Total Distance and t for cycles

Substitute values for Base Cycle and Rate

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
