Abox without a top is made from a rectangular piece of cardboard, with dimensions 40 inches by 32 inches, by cutting out square corners with side length x inches. which expression represents the volume of the box in terms of x? (a) (40−2x)(32−2x)x (b) (40−x)(32−x)x (c) (2x−40)(2x−32)x (d) (40−2x)(32−2x)4x

(a) (40−2x)(32−2x)x

Step-by-step explanation:

A box without a top is made from a rectangular piece of cardboard, with dimensions 40 inches by 32 inches, by cutting out square corners with side length x inches. both sides are cut by x inches

Length of the box = 40 -x-x= 40-2x inches

Width of the box = 32-x-x= 32-2x inches

height of the box is the side length = x inches

Volume of the box = length * width * height

= (40-2x)(32-2x)x

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%
