Answer:

(-2, -1).

Step-by-step explanation:

y = x² + 4x + 3

Completing the square:

y = (x + 4/2)^2 - (4/2)^2 + 3

y = (x + 2)^2 - 4 + 3

y = (x + 2)^2 - 1.

This is vertex form and the coordinates of the vertex are (-2, -1).

Amanda [17]

Answer:

In short, they are all quadrilaterals.

Step-by-step explanation:

<u>Rectangle:</u>

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

<u>Square:</u>

- Every angle equals 90 degrees

- Opposite sides are equal and parallel

- Diagonals within the square are perpendicular

<u>Parallelogram:</u>

- Opposite sides are equal and parallel

- Opposite angles are equal

- Any two angles next to each other have to equal 180 degrees, since it would be a line

<u>Rhombus:</u>

- Opposite angles are equal

- All sides are equal

- Opposite sides are parallel

- Diagonals within the square are perpendicular

- Any two angles next to each other have to equal 180 degrees, since it would be a line

<u>Trapedzoid:</u>

- There is only one pair of parallel lines

<u>Kite:</u>

- There are two pairs of equal signs

- There are two equal angles

- You can look at it like two equal triangles glued together

Really hope this helped you!
