C= 5\9 (f−32) the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true? i.) a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of 5\9 degree celsius. ii.) a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit. iii.) a temperature increase of 5\9 degree fahrenheit is equivalent to a temperature increase of 1 degree celsius. a) i only b) ii only c) iii only d) i and ii only

i'm not sure i quite understand, could you provide more information?

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".

answer: haha (: i’ll go see what it is
