Eric noticed that his basil plant grows 5 cm every day. he starts recording the height when the plant is 22 cm tall. how many days has he been recording the growth of the plant, if it is now 62 cm tall? eric sets up and solve the equation shown. what does the solution 8 mean?

y = 5x + 22
62 = 5x + 22
40 = 5x
x = 8

8 days

Step-by-step explanation:

If Eric's basil plant grows 5 cm per day and he records the height when it is 22 cm tall. The plant grows until it is 62 cm.

Let y be the the height of the plant at 62 cm and x be the number of days that he has been recording. We can multiply the growth per day, which is 5, to the number of days it has grown and add the starting growth. Therefore the equation will lool like this:

We can simplify the equation because we know that y=62:

Therefore we can solve for x:

The number of days Eric has been recording the plant growth is 8 and his analysis is correct.

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".

final total: 63
