The figure below is a cube, all edges are the same, but I don’t know how to figure this out please help!

cmd+shift+4 = screnshot

Step-by-step explanation:

1.

((2x + (3x + 2)) × 2 = 10x + 4

2.

(4x + 3) × 2x = 8x² + 6x

3. volume = width × length × height

2x × (3x + 2) × (4x + 3) = (6x² + 4x) × (4x + 3) = 24x³ + 18x² + 16x² + 12x

= 24x³ + 34x² + 12x

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
