Answer:  \\The\: width\: is \: 6 \:  {in}^{2}  \\ \\  Step\: by\: step\: explanation: \\ Let \:  x  \: be \:  the  \: width  \: of  \: the \:  rectangle,\: x > 0\Rightarrow the \: length:2x + 8 \\ We  \: have  \: an \:  equation:x(2x + 8) = 120 \\ \Leftrightarrow 2 {x}^{2}  + 8x  + 8= 128 \\ \Leftrightarrow  {x}^{2}  + 4x   + 4 = 64 \\ \Leftrightarrow {(x + 2)}^{2}  = 64 \\ \Leftrightarrow x + 2 =  \pm8 \\ \Leftrightarrow x = 6 \:  \vee \: x =  - 10 \\ \Rightarrow x = 6 \: (x > 0)

sasho [114]

Answer:

The line between 1 5/8 and 1 7/8 is exactly 1 3/4.

Step-by-step explanation:

1 3/4 = 1 6/8

Since the lines are every 1/8 of a cup, there are a total of 16 lines indicating 1/8 of a cup for a total of two full cups.

1/8 less than 1 6/8 is 1 5/8.

1/8 more than 1 6/8 is 1 7/8.

The line between 1 5/8 and 1 7/8 is exactly 1 3/4.
