Find the area of the figure. round to the nearest tenth if necessary

465in

Step-by-step explanation:

1. Find out how much of the figure is missing. What i did is find out how much of the width is missing. as you can see it is 7in. For the length you are missing 5in.

2. then multiply 25 by 20. this equals 500

3. multiply 7 to 5. which equals 35

4. lastly subtract 500 to 35 which gives you 465 in.

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".
