timama [110]

Answer:

92 sq. inches

Step-by-step explanation:

Total paper required = total surface area

Surface area of a cuboid = 2[(l×b) + (l×h) + (b×h)],

Where 'l' is the length, 'b' is the breadth and 'h' is the height

For the box, total surface area = 2[(8×3) + (3×2) + (8×2)]

=2[24 + 6 + 16]

=2[46]

= 92 sq. inches

2X+4=20+5X<br>A)1/2 B)-1/2 C)2 D)-2​
Nookie1986 [14]

Answer:

It seems that your options aren't correct as the right answer is -5.3333... (recurring)

Step-by-step explanation:

1)  2x + 4 = 20 + 5x   (subtract by the smallest unknown)

  -2x                  -2x

2)  4        = 20 + 3x

    -20      -20    (now subtract each side by 20 as we want to leave the unknown on one side and another number on the other side.

3) -16       = 3x   (Divide each side by 3)

   ÷3        = ÷3

4) -5.33333... = x

<h3>Now we have found x but if you're unsure you can substitute to see if your answer is correct.</h3><h3>2 x -5.3333 + 4 = -6.6666</h3><h3>20 + 5 x -5.3333= -6.6665</h3><h3>Our answer is correct! (When answers are rounded, it is equal to the same thing).</h3>
