Best ResponseYou've already chosen the best response.2Correct, that gives us: \(\sf 4.5[2x  0.9]\) Now distribute 4.5 into the parenthesis..do you know how?

Best ResponseYou've already chosen the best response.2I just made another mistake..lol. It would actually give us: \(\sf 4.5[2x  (0.9)]\) Or \(\sf 4.5[2x + 0.9]\)

Best ResponseYou've already chosen the best response.2Okay, when we distribute, we take the number outside of the parenthesis and multiply it to everything inside the parenthesis.

Best ResponseYou've already chosen the best response.2So \(\sf 4.5[2x + 0.9]\) becomes \(\sf (4.5 \cdot 2x) + (4.5 \cdot 0.9)\) Can you simplify that?

Best ResponseYou've already chosen the best response.2It's \(\sf 2x\), not \(\sf 2\).

Best ResponseYou've already chosen the best response.2Multiply 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 \(\sf 4.5 \cdot 2x\)?

Best ResponseYou've already chosen the best response.2Correct! So we have: \(\sf 9x + (4.5 \times 0.9)\)

Best ResponseYou've already chosen the best response.2Yes, we have: \(\sf 9x  4.05\) That's our answer..we can't combine them since they're not like terms.
