Andrews [41]

Answer:

x = -1

Step-by-step explanation:

2(x – 2) + 6 = 0

2x - 4 + 6 = 0

~Combine like terms

2x + 2 = 0

~Subtract 2 to both sides

2x = -2

~Divide 2 to both sides

x = -1

Best of Luck!

Three consecutive integers have a sum of 168. What is the value of the largest integer
Svet_ta [14]
Largest integer: 57

x + x + 1 + x + 2 = 168 
3x + 3 = 168
-3             -3
3x       = 165
/3             /3 
x         = 55 

x = smallest integer = 55
x + 1 = middle integer = 55 + 1 = 56
x + 2 = largest integer = 55 + 2 = 57

= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x</span>
