Answer:
between 10 and 22
Step-by-step explanation:
A side of a triangle must measure between the difference of the lengths of the other two sides and the sum of the lengths of the other two sides.
Difference: 16 - 6 = 10
Sum: 6 + 16 = 22
Answer: between 10 and 22
7(3a + 12) = 168 ← ( divide both sides by 7 )
3a + 12 = 24 ← ( subtract 12 from both sides )
3a = 12 ← ( divide both sides by 3 )
a = 4
OR
distribute the parenthesis by 7
21a + 84 = 168 ← ( subtract 84 from both sides )
21a = 84 ← ( divide both sides by 21 )
a = 4

Answer:
k = 5
Step-by-step explanation:
Given that (x + 1) is a factor of f(x) then f(- 1) = 0
f(- 1) = 3(- 1)³ + 2(- 1) + k
= 3(- 1) - 2 + k
= - 3 - 2 + k
= - 5 + k
Then - 5 + k = 0 ( add 5 to both sides )
k = 5
