Answer:
45
Explanation:
Solving for d, we find ...
3(d +1) = 4(d -2)
3d +3 = 4d -8 . . . . . . eliminate parentheses
11 = d . . . . . . . . . . . . subtract 3d-8
Then the value of 5(d-2) is ...
5(11 -2) = 5(9) = 45
_____
The graphical solution gives both the value of "d" and the value of 4(d-2). To get 5(d-2), we only need to add d-2 to the value of 4(d-2).
5(d-2) = (11 -2) +36 = 45
