Celine's cereal company is launching a new brand of cereal and she is considering two different sizes for the base of the boxes. box 1: the length is 3 times the width. box 2: the length is 1 less than 4 times the width. the dimensions of the base of box 1 are: width: x; length: 3 width: x; length: x + 3 width: x; length: x – 3 width: x; length: 3x

D. Width = x and Length = 3x

Step-by-step explanation:

We are given that,

The length of Box 1 is 3 times the width of Box 1.    (1)

Let the width of Box 1 = x

So, from (1), we have,

Length of Box 1 = 3 × Width of Box 1

i.e. Length of Box 1 = 3x

Thus, the dimensions of Box 1 are : Width = x and Length = 3x

Hence, option D is correct.

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c
