Answer:

16  4/5  inches

Step-by-step explanation:

We can find the amount it will grow by taking the rate it grows times the time

growth = rate* time

            = 2 2/5 * 7

    Changing the mixed number to an improper fraction

2 2/5 = (5*2+2)/5 = 12/5


growth = (12/5)*7

             =84/5  inches

Changing this back to a mixed number

5 goes into 84  16 times  (5*16 = 80  )  with 4 left over

16  4/5  inches

Can someone give me some tips of how to study. I have already tried writing everything in my lesson but it doesn't seem to work
Ainat [17]
Study all notes, reread the chapters again. Have someone ask questions on the chapters page by page. This always has worked for me. Plus try to do this again the night before the test. You will be surprised how much you can remember by doing it again the night before the test. Hope this helps.

Can you draw a trapoziod with three right angels
artcher [175]
Yes. A trapezoid is defined as a <span>quadrilateral with two sides parallel, so a trapezoid with three right angles is just a square!</span>
