To find the perimeter:

First, add all the sides together and find x

2x + 3 + 5x + 8 + x + 7x - 2 = 15x + 9

15x + 9 is your answer (for you cannot simplify it anymore)

hope this helps

There was 2/3 of pan of lasagna in the refrigerator. Bill and his friends ate half of what was left. Write a number sentence and

Veseljchak [2.6K]

Half of 2/3 is:

$\frac { 1 }{ 2 } \times \frac { 2 }{ 3 } =\frac { 1 }{ 3 }$

This means that 1/3 was left. This also means that they ate 1/3 of the lasagne.
