Answer:  The correct option is (B) HB = HB'.

Step-by-step explanation:  Given that polygon ABCD is reflected across EF to make polygon A'B'C'D'.

We are to select the correct statement from the given options.

Since EF is the line of reflection, so the distance of each vertex of the original polygon ABCD is equal to the distance of the corresponding vertex of the reflected polygon A'B'C'D'.

That is,

The corresponding vertex of B is B'.

We know that the distance of a point form a line is the length of the perpendicular drawn from the point to the line.

Since HB and HB' are both perpendiculars to EF, so the distance of the vertex B from EF is HB and the distance of the vertex B' from EF is HB'.

Since both B and B' are equidistant from the line EF, so we must have

HB = HB'.

Thus, the correct statement is  HB = HB'.

Option (B) is correct.

Answer:

This is true.

Step-by-step explanation:

Step 1: see that √27 is the same as √3*3*3 and thus 3√3

Step 2: remove parenthesis so that 2(1-3√3) becomes 2 - 6√3

Step 3: observe that the equation now becomes 6√3 + 2 - 6√3 = 2

if you simplify any further, you are left with 0=0, which is true.

Comment if there is any step that requires more details...

How many negative roots will this function have? f(x) = x^7 – 2x^4 + 7x^2 + 2x – 2<br> help plsss
Vikentia [17]

There are two negative roots to the provided polynomial function

f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2

<h3>What is polynomial?</h3>

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n

We have a polynomial function:

f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2

\rm f(x) =\left(x+1\right)\left(x^6-x^5+x^4-3x^3+3x^2+4x-2\right)

Using the zero product property:

\rm \left x+1\right = 0 \ \ \ or \left x^6-x^5+x^4-3x^3+3x^2+4x-2\right = 0

After solving:

x = -1, x = -0.853, and x = 0.418 (using the graph method)

Thus, there are two negative roots to the provided polynomial function

f(x) = x⁷ – 2x⁴ + 7x² + 2x – 2
