Answer:

$\boxed{ \bold{ { \boxed{ \sf{(11y + m)(11y - m)}}}}}$

Step-by-step explanation:

$\sf{121 {y}^{2} - {m}^{2} }$

$\longrightarrow{ \sf{ {(11y)}^{2} - {(m)}^{2} }}$

Use the formula of a² - b² = ( a + b ) ( a - b )

$\longrightarrow{ \sf{(11y + m)(11y - m)}}$

Hope I helped!

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.

Answer:

F. x ≤ -5

Step-by-step explanation:

Translating the diagram to more conventional symbols, we have ...

4x +12 ≤ -8

4x ≤ -20 . . . . . . . subtract 12 from both sides

x ≤ -5 . . . . . . . . . divide both sides by 5
