Answer: It’s D) 9x +6
Step-by-step explanation:
(3x+2)+2(3x+2)
you do distributive property
3x+2+6x+4
then combine like terms
= 9x+6
Both of these are linear functions:
Distance A is d=2.5h and is proportional to time because the distance is just 2.5 times however many hours you have traveled.
Distance B is d= 2(h-1) + 4. This is not proportional to time but it is a linear function.
Ooh so the directions tell us what we need to find the entire line, which is made up of FH. so just add GH (15) and FG (6) together to find FH. so that is 21. FH=21.
