Answer:

The answer would be A

Step-by-step explanation:

1^2=1×1= 1

2^2 =2×2=4

3^2=3×3=9

4^2=4×4=16

Therefore,

√11 lies between 3 and 4

Answer:

Step-by-step explanation:

$since 3 is \sqrt{9} and 4 is \sqrt{16} then it follows that \sqrt{11} is between the two$

Rhombus CDEF with vertices<br> C(-5, 5), D(-1,7), E(-3, 3), and<br> F(-7, 1): 270° counterclockwise

Bogdan [553]

The required coordinates of the pre image are C'(-5, -5), D' (7, 1), E' (3, 3) and F' (1, 7)

<h3>Rotation of coordinates</h3>

Rotation is a way of changing the position of an object on an xy plane.

When a coordinate point (x, y )is rotated 270 degrees counterclockwise, the resulting coordinate point will be (y,-x)

The x-coordinate is negated and then swapped.

Given the coordinates of a Rhombus CDEF with vertices <u>C(-5, 5), D(-1,7), E(-3, 3), and F(-7, 1)</u>, the resulting coordinate points will be;

C(-5, 5) = C'(-5, -5)

D(-1,7) = D' (7, 1)

E(-3, 3) = E' (3, 3) and

F(-7, 1) = F' (1, 7)

Hence the required coordinates of the pre image are C'(-5, -5), D' (7, 1), E' (3, 3) and F' (1, 7)

What type of quadrilateral is quadrilateral ABCD if AB=4x-2, BC=2x+12, DC=3x+5, AD=6x-16, AC=4x+12, DB=8x-10, and x=7? Explain a

ivanzaharov [21]

Answer:

The quadrilateral ABCD is a square.

Step-by-step explanation:

According to the statement, AB, BC, CD and DA are the sides of the quadrilateral, whereas DB and AC are its diagonals. If we know that $x = 7$ , $AB = 4\cdot x - 2$ , $BC = 2\cdot x + 12$ , $DC = 3\cdot x +5$ , $AD = 6\cdot x -16$ , $AC = 4\cdot x + 12$ and $DB = 8\cdot x -10$ , the lengths of each line segment are respectively:

Sides

$AB = 4\cdot (7) -2$

$AB = 26$

$BC = 2\cdot (7) +12$

$BC = 26$

$DC = 3\cdot (7) +5$

$DC = 26$

$AD = 6\cdot (7) -16$

$AD = 26$

Diagonals

$AC = 4\cdot (7) +12$

$AC = 40$

$DB = 8\cdot (7) - 10$

$DB = 40$

This information indicates that this quadrilateral is a square because of these characteristics:

1) All sides have the same length.

2) The ratio of any diagonal to any side is $\sqrt{2}$ .

Pls help I need this

yulyashka [42]

Step-by-step explanation:

I hope this helps, you take the substitution and put it in where the variable once was in parenthesis, then you let them interact as the vaiable onece was but now you can solve because you know the value.
