What is the surface area of the box
Elena-2011 [213]

Answer:

<u>360 in²</u>

Step-by-step explanation:

Surface Area of the box = 2(lb+bh+hl)

                                        = 2(12×6 + 6×6 + 6×12)

                                        = 2(72 + 36 + 72)

                                        = 2(180)

                                        = <u>360 in²</u>

<u />

Therefore D is the right answer.

A glass top of an office table is in the form of rectangle. The diagonal of the table have length 5x-11 and 2x+25
3241004551 [841]

Answer:

1) The value of x is 12.

2) The length of the diagonal is 49.

Step-by-step explanation:

1) If the glass is a rectangle, then both diagonal must have the same length, that is, the following equation must be solved:

5\cdot x - 11 = 2\cdot x + 25 (1)

We need some algebraic handling to determine the value of x:

5\cdot x - 11 = 2\cdot x + 25

5\cdot x - 2\cdot x = 25 +11

[5+(-2)] \cdot x = 36

3\cdot x = 36

x = 12

The value of x is 12.

2) If we know that x = 12, then the length of the diagonal (d) is:

d = 2\cdot x + 25

d = 49

The length of the diagonal is 49.
