Use the FOIL method (first, outside, inside, last) to multiply:
2x^2-8x+3x-12
This can be simplified even more into:
2x^2-5x-12.
Hope this helped!
Answer:
No
Step-by-step explanation:
It would take 1 painter 32 hours to paint a house (because 4*8=32). If we divide 32 by 12 we get 3, so no, it is not a direct variation because if it was it would only take 3 hours for the 12 painters to paint the house.
First find the volume of the box:
V=2*2.2*2.5=11 cm^3
Then find the desity given by grams divided by volume:
density=25.6 g/ 11 cm^3 = 2.327 g/cm^3
Round to the nearest tenth, so 2.3 g/cm^3.
I hope that helped.
