The equation of a circle centered at the origin with a radius of unit length is x2 + y2 = 1. this equation changes if the center of the circle is not located at the origin or the radius is not of unit length. you will use the geogebra geometry tool to examine how the equation of a circle changes as you move the center and change the radius. go to equation of a circle , and complete each step below. if you need , follow these instructions for using geogebra.

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".

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
