Asolid figure can be located on a three-dimensional cartesian coordinate system. a. true b. false

The answer is (A) TRUE.

Step-by-step explanation: The given statement is

"A solid figure can be located on a three-dimensional Cartesian coordinate system."

We are to check whether the above system is true or false.

We know that a solid figure has three dimensions, so we can obviously locate the figure on a three dimensional plane. The three dimensions are plotted against the three axes, X-axis, Y-axis and Z- axis. For example, see the attached figure of a solid tetrahedron on a three dimensional plane.

Thus, the answer is YES, the given statement is true.

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".
