Which expressions are equivalent to 2(4x−3)+3x−12(4x−3)+3x−1 ?

Select each correct answer. Multiple choice.
A. 8x+3x−4
B. 5x−1
C. 2(3x−3)+5x−1
D. 11x−7

Answer :

apologiabiology
I see you accidentally pasted the expression 2(4x-3)+3x-1 twice, so

expand 2(4x-3) to get
2(4x)+2(-3)=8x-6

now we have
8x-6+3x-1
regrouping we get
8x+3x-6-1
adding like terms
11x-7


A is 11x-4, not 11x-7, wrong
B is wrong
C. hmm, 6x-6+5x-1=11x-7, yep
D is the same, we can see



C and D are correct
