Answer:
(m-4) / (5m)
Step-by-step explanation:
((m²-16) / (5m)) / (m+4) =
(m²-16) / (5m(m+4)) =
m²-16 / (5m²+20m) =
(m-4) / (5m)
There is only one solution
When you graph both equations, they intersect therefore the intersection point tells you there is one solution. If it was infinitely many solutions then it would be the same line. If it was no solution then the graph would show to parallel lines.
Answer:
24/7
Step-by-step explanation:
tan 2t =+ 2 tan t) /( 1 - tan²t)
(2(-4/3))/(1- 16/9)
(-8/3)/(-7/9) = 24/7
Answer:
(x - 3)(4x² + 6x + 9)
Step-by-step explanation:
This is a difference of cubes which factors in general as
a³ - b³ = (a - b)(a² + ab + b²)
8x³ = (2x)³ ⇒ a = 2x
27 = 3³ ⇒ b = 3
Hence
8x³ - 27
= (2x)³ - 3³
= (2x - 3)( (2x)² + (2x × 3) + 3²)
= (2x - 3)(4x² + 6x + 9)
Well the first term = 1 because (n - 1) = 0 for the first term
So its either A or D
4th term = 1 + (4 - 1)(-5.7 = 1 + 3*-5.7 = -17.1
Its C
