River used the Remainder Theorem to find the remainder of (x^3-2x^2-68x-120)divided by(x+2) and got a remainder of 0. What does this mean? A) It means -2 is a factor and x= -2 is a root.
B) It means (x+2) is a factor and x= -2 is a root.
C) It means (x-2) is a factor and x= 2 is a root.
D) It means 0 is a factor and x= 0 is a root.

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".

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

sorry i just needed points for a quiz plz for give me

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
