The table shows the heights and the lengths of several rectangles. Height (in.) 41 7021 34 10 92 54 24 10 35 42 66
Length (in.) 21 25 32 12 16 45 40 2345 35 21 14
What does the correlation coefficient for the data indicate about the strength of the linear
association between the height and the length of these rectangles?
A. Weak negative correlation
B. Strong negative correlation
C. Weak positive correlation
D. Strong positive correlation

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".

step-by-step explanation:

sry but any answer choices
