Answer:

  (x +2)(2x +1)

Step-by-step explanation:

The factors are the set of tiles down the left side: x + 1 + 1 = (x +2), and the set of tiles across the top: x + x + 1 = (2x +1)

Your factored form is shown in choice D:

  (x +2)(2x +1)

_____

<em>Additional comment</em>

The point of this sort of diagram is to show you how the factors work together to give you the product. Each tile in the middle of the figure represents the product of the tile on the top line and the tile in the left column.

The product of x and x is x².

The product of 1 and x is x.

The product of 1 and 1 is 1.

The product of the two factors is the sum of all the tiles in the middle of the diagram: 2x² +5x +2.

A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
NeTakaya

Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle =\dfrac{7\pi}{10}

Arc length = 33 cm

Formula for arc length :

s=r\theta

where, s is arc length, r is radius and \theta is central angle in radian.

Substitute s=33 and \theta=\dfrac{7\pi}{10} in the above formula.

33=r\left(\dfrac{7\pi}{10}\right)

Multiply both sides by 10.

330=7\pi r

Divide both sides by 7\pi.

\dfrac{330}{7\pi}= r

Put \pi=3.14

\dfrac{330}{7(3.14)}= r

15.0136= r

r\approx 15

Therefore, the radius of the circle is 15 cm.
