Factorise:(1) r- 2x -x+2(ii) x + 13x2+32x+ 20(i) x - 3x2 - 9x - 5(iv) 2y3 + y2 - 2y-1​

Answer»

iii) 2y³ + y² - 2y - 1 = (2y+1)(y+1)(y-1)

Step-by-step EXPLANATION:

Factorising 2y³+y²-2y-1

= y²(2y+1)-1(2y+1)

=(2y+1)(y²-1)

=(2y+1)(y+1)(y-1)

By ALGEBRAIC IDENTITY:

a²-b²= (a+b)(a-b)*/

Therefore,

2y³+y²-2y-1 = (2y+1)(y+1)(y-1)

Find the curved surface area and the total surface area of the cylinder for which :(i) h = 30 cm and r = 14 cm(ii) h = 32 cm and r = 10.5 cm(iii) h = 35 cm and r = 21 cm(iv) h = 5 m and r = 35 cm​

Answer»

Step-by-step explanation:

Curved surface area :

i) h = 30 cm, R = 14 cm

csa = 2πrh

=> 2 x 22/7 x 14 x 30

=> 2640

ii) h = 32 cm, r = 10.5 cm

csa = 2πrh

=> 2 x 22 / 7 x 10.5 x 32

=> 2112

III) h = 35 cm, r = 21 cm

csa = 2πrh

=> 2 x 22 / 7 x 21 x 35

=> 4620

iv) h = 5 cm, r = 35 cm

csa = 2πrh

=> 2 x 22 / 7 x 35 x 5

=> 1100
