Answer:

{x}^{2}  - x - 2 \\  {x}^{2}  - 2x + 1 x- 2 \\  {x}^{2}   + 1x - 2 x- 2 \\ x(x + 1) - 2(x + 1) \\  = (x + 1)(x - 2)

Suppose ABCD is a rhombus with AB = 12 inches. The midpoints of its sides are joined to form a quadrilateral. What type of quadr
MrRissso [65]

Answer:

A rectangle

Step-by-step explanation:

The given parameters are;

The quadrilateral ABCD is a rhombus;

The length of the sides of the rhombus = 12 inches

The lengths of the sides of a rhombus are equal

The opposite interior angles of the rhombus are equal

The length of each midpoint from the vertex = 12 in./2  = 6 in.

Therefore, we have;

The line joining the midpoints form a quadrilateral with the length of the opposite sides equal

The sum of the interior angles of the rhombus = 180°

From the diagram created with Microsoft Visio, we have;

4·a + 4·b + 360 = 4 × 180 = 360 + 360

4·a + 4·b = 360

a + b = 90°

We have;

The interior angles of the quadrilateral formed = x

a + b + x = 180° Sum of angles on a straight line

∴ x = 180° - (a + b) = 180° - 90° = 90°

x = 90°

Therefore, the interior angles of the quadrilateral formed = 90°

The quadrilateral formed having equal opposite sides, and all interior angle of 90° each is a rectangle

David is making baskets of fruit he has 12 apples and 20 pears what is the greatest number of baskets he can make
Fiesta28 [93]
He can make 12 baskets i’m pretty sure because if he only has 12 apples you have to put the same with the pears if that makes sense

IceJOKER [234]
Answer:

(x + 2) (x + 4)

Step-by-step explanation:

Before looking at my explanation make sure next time you are going to ask another question write the numbers that include exponents like this: x^2 instead of x2

Factor out x^2:

x + x

Factor out 6x:

Since it is in the bx form we’ll need two numbers be add so it can be equivalent to 6x

Answer: 4 and 2

Factor out 8:

4 x 2

Now start with the 8 and 6x

(? + 4) + (? + 2)

Then finish it off with x

(x + 4) (x + 2)
