Answer:
Area of the sector = 57.26295cm²
Step-by-step explanation:
Radius of the circle=9cm
π= 3.142
Angle at B= 81° ( opposite angle of a quadrilateral)
Area of the sector = πr² * 81/360
Area of the sector = 3.142 * 9*9 * 0.225
Area of the sector= 3.142*81*0.225
Area of the sector = 57.26295cm²

Answer:<u>
158.7 is the answer</u></h2><h2><u>or it can be</u>
<u>89.7</u></h2>
Step-by-step explanation:
<h2>
<u>69 + Percentage increase =
</u></h2><h2>
<u>69 + (130% × 69) =
</u></h2><h2>
<u>69 + 130% × 69 =
</u></h2><h2>
<u>(1 + 130%) × 69 =
</u></h2><h2>
<u>(100% + 130%) × 69 =
</u></h2><h2>
<u>230% × 69 =
</u></h2><h2>
<u>230 ÷ 100 × 69 =
</u></h2><h2>
<u>230 × 69 ÷ 100 =
</u></h2><h2>
<u>15,870 ÷ 100 =
</u></h2><h2>
<u>158.7</u></h2><h2>

<u /></h2><h2>
<u>69 increased by 130% = 158.7
</u></h2><h2>
<u>Absolute change (actual difference):
</u></h2><h2>
<u>158.7 - 69 = 89.7</u></h2>
Step-by-step explanation:
Given
(2x + 3 )² - (2x + 3) (x - 5)
= 4x² + 6x + 9 - ( 2x (x - 5) + 3(x - 5 ))
= 4x² + 6x + 9 - ( 2x² - 10x + 3x - 15 )
= 4x² + 6x + 9 - 2x² + 10x - 3x + 15
= 2x² + 13x + 24
Hope it will help :)
