Answer: 25 < P < 36

15/4 < w < 26/4

35/4 < L < 46/4

<u>Step-by-step explanation:</u>

Perimeter is BETWEEN 25 and 36

25 < P < 36

Graph: O--------------O

25 36

Perimeter = 2L + 2w ; substitute L = w + 5

25 < 2(w + 5) + 2w < 36

25 < 2w + 10 + 2w < 36

25 < 4w + 10 < 36

15 < 4w < 26

$\dfrac{15}{4}$ < w < $\dfrac{26}{4}$

$3\dfrac{3}{4}$ < w < $6\dfrac{1}{2}$

Graph: O------------------------O

$3\dfrac{3}{4}$ $6\dfrac{1}{2}$

Perimeter = 2L + 2w ; L = w + 5 --> w = L - 5

25 < 2L + 2(L - 5) < 36

25 < 2L + 2L - 10 < 36

25 < 4L - 10 < 36

35 < 4L < 46

$\dfrac{35}{4}$ < L < $\dfrac{46}{4}$

$8\dfrac{3}{4}$ < L < $11\dfrac{1}{2}$

Graph: O------------------------O

$8\dfrac{3}{4}$ $11\dfrac{1}{2}$

Note: Make sure you use OPEN dots when graphing.
