Answer:

$3(3m + 1)(3m - 1)$

Step-by-step explanation:

${27m}^{2} - 3$

Factorise

$3( {9m}^{2} - 1)$

Rewrite it

$3(( {3m)}^{2} - {1}^{2} )$

$3(3m + 1)(3m - 1)$

Which expression is a CUBE ROOT of -2i?

olganol [36]

Remember
∛(ab)=(∛a)(∛b)

also
i¹=i
i²=-1
i³=-i
i⁴=1

so

∛-2i=(∛2)(∛-i)=(∛2)(i)=i∛2

Please find the surface area of the cone (image attached) and reduce answer to nearest tenth, if necessary.

Luba_88 [7]

Answer:

$S.A = 135.6 yd^2$ (

Step-by-step explanation:

Surface area of cone is given as:

Surface Area (S.A) = πr(r + l)

Where,

$r = radius = 3 yd$

$l = slant height = 11.4 yd$

Take π as 3.14

Plug the given values into the formula to find the surface area.

$S.A = 3.14*3(3 + 11.4)$

$S.A = 9.42(14.4)$

$S.A = 135.6 yd^2$ (rounded to the nearest tenth)
