It's an expression that can be simplified to read
( 0.7 x 0.4 ) ( b³ x b⁹ )
= ( 0.28 ) ( b¹² ) = 0.28 b¹² .
N(2n+6)-(n²-1)= 2n²+6n-n²+1=n²+6n+1
Answer:
x = ± 4
Step-by-step explanation:
given 3x² = 48 ( divide both sides by 3 )
x² = 16 ( take the square root of both sides )
x = ±
= ± 4
x ∈ {- 4, 4 }
37.68 is the answer
