Answer:
-16x+14.8
Step-by-step explanation:
2(x+7)-2(9x-0.4)
2x+14-18x+0.8
-2x+14-18x+0.8
14-16x+0.8
14+0.8-16x
14.8+-16x
Answer:
f(x) = 488
Step-by-step explanation:
first you plug in 82 in for x then you multiply by 6 times 82 and you get 492 then you subtract 4 and you get 488
Milli means 1000
1 meter=1000 milimeters
therefor
9 times 1 meter=9 times 1000 milimeters
9 meter=9000 milimeters
