The volume of a rectangular box is (x3 - 7x2 - 9x + 63) cubic units. Determine the dimensions of the rectangular box by factoring the volume expression completely.

Answers

Answer 1

Answer: Hello,
well done.
As x^3-7x²-9x+63=(x-3)(x+3)(x-7) we must have x>3 and x>-3 and x>7 thus x>7

Explanations:
x^3-7x²-9x+63=x^3-9x+(-7x²+63)=x(x²-9)-7(x²-9)=(x²-9)(x-7)=(x+3)(x-3)(x-7)

A
Yes, because nonmetals are ductile.
Yes, because nonmetals are
malleable

Answers

1. To the question whether it is a good idea to design a drink can from a solid nonmetal, the answer is No, because nonmetals lack luster.

The Luster in Nonmetal

Non-metals do not have luster because they cannot reflect light from their surface with their dull appearances. Diamond and iodine are two exceptions to lustrous non-metals.

2. The reason it is not a good idea designing a drink can from a solid nonmetal is No, because nonmetals are brittle. Generally, solid nonmetals are known to be dull and brittle. They can easily break into pieces.

Thus, non-metals are not ductile or malleable.

What are the coordinates of B and how is that the answer ?

Answers

Step-by-step explanation:

Point A = (-1, -3).

Midway of AB = (-3, 2).

Let Point B = (x, y).

Then (-1, -3) - (-3, 2) = (-3, 2) - (x, y).

=> (2, -5) = (-3-x, 2-y).

We have -3 - x = 2 and 2 - y = -5.

So x = -5 and y = 7.

Hence, point B = (-5, 7).
