$1km=1,000m\\therefore\ 104km=104\times1,000m=\boxed{104,000m}\\\\1m=100cm\to1cm=0.01m\\therefore\ 480cm=480\times0.01m=\boxed{4.8m}\\\\1kg=1,000g\\therefore\ 5.6kg=5.6\times1,000g=\boxed{5,600g}\\\\1cm=10mm\to1mm=0.1cm\\therefore\ 8mm=8\times0.1cm=\boxed{0.8cm}$

HELP ASAP

vova2212 [387]

Answer:

1. A. 4 terms

There are 4 different values in the expression, so therefore there are 4 terms.

2. D. 3x^2 + 6x + 10

To get the answer...

start with the original expression: 3x^2 + x + 10 + 5x

add the like terms together, in this case you'd add x + 5x

you'll get: 3x^2 + 6x + 10

I hope I could help :)
