Answer:
-9
Step-by-step explanation:
2(n+6) -15 = 5n+18
2n + 12 - 15 = 5n + 18
2n - 3 = 5n + 18
2n = 5n + 21
-3n = 21
n = -9
Answer: the answer is 21
Step-by-step explanation:
If 24 is a solutoin of x, n has to be 24 squared. 24*24=576
Answer:
19
Step-by-step explanation:
Given 2 sides of a triangle then the third side x is

18 - 2 < x < 18 + 2
16 < x < 20
Then the largest possible length of the third side is 19
