2(n - 1) + 4n = 2(3n - 1)
2n - 2 + 4n = 6n -2
6n - 2 = 6n - 2 (equal)
6n - 6n = 2 - 2
0 = 0
whatever value you put into the place of n, you'll get 0 = 0
Answer: (C) 4
Have a good day.
Examples of rational numbers are: -2 = -2/1, -5 = -5/1, -14 = -14/1, 1/2, 2/3, 5/8, 3/4, 17/5, . 6 = 6/10 = 3/5, . 25 = 1/4, . 33 = 33/100, 2¾ = 11/4, 3⅓ = 10/3, .
Answer:
just sub in the numbers into the equation to replace the X ..
example for
a) h(7) : 44
Step-by-step explanation:
h(7) : x^2 -5
sub in 7 into the equation to replace X
so you get
(7)^2 - 5
49-5
44
