Answer:

  60+16√30 cm² ≈ 147.64 cm²

Step-by-step explanation:

You can figure the height of the object from ...

  V = Bh

  120 cm^3 = (30 cm^2)h

  4 cm = h . . . . . divide by 30 cm^2

However, this is insufficient to tell you the surface area.

__

If you assume that the base is square, then its side length is

  A = s^2

  s = √A = √(30 cm^2) = (√30) cm

The lateral surface area can then be found from the perimeter of the base and the height

  LA = Ph = (4√30 cm)(4 cm) = 16√30 cm^2

The total surface area will be the sum of this lateral area and the area of the two bases:

 total area = 16√30 cm^2 +2·30 cm^2

 total area = (60 +16√30) cm^2 ≈ 147.64 cm^2

__

For any other shape, the total area will be larger. It can be arbitrarily large, unless limits are put on the dimensions of the object.

Determine the truth value of each statement based on the expression.
adoni [48]

1. True. The four terms are {6x², -2x, -14y, 3x}

2. False. x³ ≠ x, so the constellation of variables is different, making the terms unlike.

3. False. The coefficient of y is -14. (Definitions vary, so I believe <em>this could be argued both ways</em>. Refer to your text or reference material for a definitive answer.)

4. False. The simplified expression is 6x² +x -14y. The coefficient of x is (-2+3)=1.

5. True. The commutative property of addition lets you interchange the addends in parentheses:

... 6x² + (-2x) + (-14y +3x) ⇒ 6x² + (-14y +3x) + (-2x)

_____

Regarding the coefficient of y: some definitions of polynomial say that operations between terms can include addition or subraction. This allows you to consider the -14y in the expression to be either of "subtracting 14y" or "adding -14y". Your viewpoint determines whether you consider the coefficient to be 14 or -14. (Personally, I like to keep signs with numbers, which is why I listed -14y as one of the terms in question 1, and why I answered question 3 as False.) If it were -14², the order of operations requires you to consider 14² to be subtracted. If y had the value -1, you would be adding the term 14. Many people would evaluate the term as -14(-1) = 14, rather than -(-14).
