The square root of 91x cannot be simplified.
insert the understood constant in front of x so it becomes 91x -1x and then subtract the constants and you get 90x.
The GCF is 13.
That doesn't factor neatly. Applying the quadratic formula, we find two real solutions: -8 plus or minus the square root of 91x = 1.5393920141694561x = -17.5393920141694561
The GCF is 13xy.
The GCF is 13xy.
x + 3 + 2x = x + 9 x + 2x + 3 = x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 1x - 1x + 2x + 3 = 1x - 1x + 9 2x + 3 = 9 2x + 3 - 3 = 9 - 3 2x + 3 - 3 = 9 - 3 2x = 9 -3 2x = 6 2x/2 = 6/2 2x/2 = 6/2 x = 6/2 x = 3
There is no country code +191. Country code +1 is the US, Canada, and some nearby islands, and all nine +1 91X codes are in the US, but you need the next digit to narrow down the area further. For example, +1 913 is in Kansas, +1 916 is in California, and +1 919 is in North Carolina. There should be exactly 8 more digits after +1 91. Country code +91 is India.

Area code 020 is used for London landlines, which have eight digit local numbers. Mobile phones (07xxx) and special-rate services (03xx and 08xx) use their own country-wide prefixes.To call from abroad, use the country code +44 and the full UK number minus its leading zero. For example:Landline 020 7946 0029 becomes +44 20 7946 0029Mobile 07345 123456 becomes +44 7345 123456
