Answer:

  2. -(-73) is positive

Step-by-step explanation:

It's not too difficult, but you can get wrapped around the axle. Here are the rules:

  • the opposite of a positive number is a negative number
  • the opposite of a negative number is a positive number

That is, turning a number to its opposite is just changing its sign.

__

If you layer these rules, you find ...

  the opposite of (<em>the opposite of a positive number</em>) is a positive number

The first rule tells you <em>the statement in parentheses is a negative number</em>, and the second rule tell you its opposite is a positive number.

That is, a double opposite gets you back where you started. In short, <em>any even number of minus signs cancel each other</em>.

__

The numbers you have listed here* are ...

  1. -730 (negative)
  2. -(-73) = 73 (positive)
  3. -75 (negative)
  4. -(-(-701)) = -701 (negative)

_____

* We say "listed here" because we're seeing mismatched parentheses and brackets, so we know something is missing. We're going by the signs and numbers that we do see. YMMV

The area of rectangular field is (49m2-42m+9).Find the dimensions of the field
Drupady [299]

Answer:

The dimensions are (7m-3) by (7m-3)

Step-by-step explanation:

We have the area of the rectangular field to be:

49 {m}^{2}  - 42m + 9

We need to factorize this expression.

Let us rewrite to obtain:

{(7m)}^{2}  - 2(7 \times 3)m +  {3}^{2}

We can easily see that the expression is actually a perfect square trinomial.

This gives us:

(7m - 3)^{2}

Or

(7m - 3)(7m - 3)

Which statement is true?
Rom4ik [11]

Answer:

  (b)  Both vertical and horizontal reflection

Step-by-step explanation:

The figure will be a horizontal reflection of itself about any vertical line through two of the smaller 6-pointed stars.

The figure will be a vertical reflection of itself about any horizontal line through two of the smaller 6-pointed stars.

  the pattern has both vertical and horizontal reflection

__

<em>Additional comment</em>

A pattern will have horizontal reflection if there exists a vertical line about which the pattern can be reflected to itself. That is, there exists one (or more) vertical lines of symmetry.

Similarly, the pattern will have vertical reflection if there is a horizontal line about which the pattern can be reflected to itself. Such a line is a horizontal line of symmetry.
