Answer:
Step-by-step explanation:
n²+2n+1 = (n+1)(n+1)
n²-8n-9 = (n+1)(n-9)
the least common denominator for these two rational expressions is :
(n+1)(n-9)
Answer:
t = 0.7
Step-by-step explanation:
s = k/t where 'k' is the constant of variation
given: 0.5 = k/7 so k = 3.5
5 = 3.5/t
5t = 3.5
t = 0.7

Answer:
x = -1/10 or -0.1
Step-by-step explanation:
-1.8 - 6x = 6(0.1 + 3x)
-1.8 - 6x = 0.6 + 18x
-6x - 18x = 0.6 + 1.8
-24x = 2.4
-x = 2.4/24
-x = 24/10 / 24
-x = 24/10 * 1/24
-x = 24/240
-x = 1/10
x = -0.1
