pickupchik [31]

Answer:

$\boxed{ \bold{ \boxed{ \sf{(3m - 4)(9 {m}^{2} + 12m + 16)}}}}$

Step-by-step explanation:

$\sf{27 {m}^{3} - 64}$

$\dashrightarrow{ \sf{( {3m)}^{3} - {(4)}^{3} }}$

Use the formula of a³ - b³ = ( a - b) ( a² + ab + b² )

$\longrightarrow{ \sf{(3m - 4)(3 {m}^{2} + 3m \times 4 + {4}^{2} }})$

$\longrightarrow{ \sf{(3m - 4)( {9m}^{2} + 12m + 16}})$

Hope I helped!

Solve For L: A = L ⋅ W ⋅ H L=aw/h L=wh/a L=a/wh L=w/ha

bonufazy [111]

Ok so what you're trying to do is get L by itself so to do this you move everything to the other side:
A=L*WH
$\frac{A}{WH}$ =L
So you answer would be: C
