I believe it is prime as you have written it.
change the end to + 81 and it factors as
(2x - 1)(x-9)(x+9)
9x9, 81x1, 3x27, 162x.5 , etc.
None but it can be simplified to: 162x-468
5x = 3x + 16Taking the 3x to the left side of the equation and changing its sign5x - 3x = 162x = 16Divide by 2x = 8
That could mean two different equations, so I'll solve both.1. (√5x)+ 7 = 13(√5x)= 65x = 36x = 36/5= 7 1/52.√(5x+7) = 135x + 7 = 1695x = 162x = 162/5= 31 2/5

2x + 4 = 162x + 4 - 4 = 16 - 42x = 122x/2 = 12/2x = 6

There is no telephone country code +162. Country code +1 is North America, including the USA, Canada, and various Caribbean and nearby islands; 62 is the first two digits of a three-digit area code. You need the next digit to narrow down the location.+1 620 = southern Kansas (excluding Wichita)+1 623 = Glendale, Arizona (part of Phoenix metro area)+1 626 = Pasadena and San Gabriel Valley, California (part of Los Angeles metro area)(The plus sign means "insert your international access prefix here." From a GSM mobile phone, you can enter the number in full international format, starting with the plus sign. The most common prefix is 00, but Japan uses 010, Australia uses 0011, and many other countries use different prefixes.)
