Answer:

The perimeter of the rectangle is 27n + 1 feet

Step-by-step explanation:

The formula of the perimeter of the rectangle is P = 2(L + W), where

L is the length of the rectangle

W is the width of the rectangle

∵ The width of a rectangle is 7n - 6.5 feet

∴ W = 7n - 6.5 feet

∵ The length of the rectangle is 6.5n + 7 feet

∴ L = 6.5n + 7 feet

→ Substitute W and L in the formula of the perimeter above

∵ P = 2[6.5n + 7 + 7n - 6.5]

→ Add the like terms

∴ P = 2[(6.5n + 7n) + (7 - 6.5)]

∴ P = 2[13.5n + 0.5]

→ Multiply the terms in the bracket by 2

∴ P = 27n + 1

∴ The perimeter of the rectangle is (27n + 1) feet

Sedaia [141]

Answer:

2hrs 40 minutes

Step-by-step explanation:

The formula for distance is expressed as:

$d=st, s=speed, t=time$

#The time taken to run:

$d=st\\\\t=d/s\\\\t_r=d/8$

#The time taken to walk:

$d=st\\\\t=d/s\\\\t_w=d/2$

#Since the distances are the same:

$d_r=8t_r,d_w=2t_w\\\\8t_r=2t_w\\\\t_r+t_w=4->t_w=4-t_r\\\\\therefore8t_r=2(4-t_r)\\\\8t_r=8-2t_r\\\\t_r=1\frac{1}{3} \hrs\\\\t_w=4-1\frac{1}{3}=2\frac{2}{3}\ hrs$

Hence, Dana spends 2hrs 40 minutes walking back
