Correct, that gives us: \(\sf -4.5[2x - 0.9]\) Now distribute -4.5 into the parenthesis..do you know how?

No lol :D
iGreen
  • iGreen
I just made another mistake..lol. It would actually give us: \(\sf -4.5[2x - (-0.9)]\) Or \(\sf -4.5[2x + 0.9]\)
iGreen
  • iGreen
Okay, when we distribute, we take the number outside of the parenthesis and multiply it to everything inside the parenthesis.
iGreen
  • iGreen
So \(\sf -4.5[2x + 0.9]\) becomes \(\sf (-4.5 \cdot 2x) + (-4.5 \cdot 0.9)\) Can you simplify that?

-13.05

that's what i got
iGreen
  • iGreen
It's \(\sf 2x\), not \(\sf 2\).
iGreen
  • iGreen
Multiply to a variable is the same as multiplying with numbers. \(\sf 3 \times 4x = 12x\) \(\sf 3 \times 4 = 12\) And we just add the 'x' next to it..so what's \(\sf -4.5 \cdot 2x\)?

-9x

@iGreen
iGreen
  • iGreen
Correct! So we have: \(\sf -9x + (-4.5 \times 0.9)\)
iGreen
  • iGreen
Multiply inside the parenthesis.

-4.05
anonymous
  • anonymous
now i have to do this -9 + -4.05
anonymous
  • anonymous
but my calculator is not working
iGreen
  • iGreen
Yes, we have: \(\sf -9x - 4.05\) That's our answer..we can't combine them since they're not like terms.
