Which procedure justifies whether-3x(5-4)+3(x-6) is equivale
e justifies whether -3X0-45+81-5) is equivalent to -12x-6?
The expressions are not equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(2)-6=-30
The expressions are not equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(3)-6=-42
The expressions are equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(-2)- 6 = 18.
The expressions are equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(1)-6=-18

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

answer: 1+1

step-by-step explanation: 1+1 is at least 2
