Answer:
x = 11, x = -11
Step-by-step explanation:
I know this is kind of late but the two previous answers were wrong.
We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.
Answer:
x=11

The number which is a multiple of 6 and a factor of 60 is 6, 12, and 30.
What are the factors?
The numbers that can divide a number exactly are called factors. There is therefore no residual after division. The numbers you multiply together to obtain another number are called factors. A factor is therefore another number's divisor.
Given digit = 60
factors of 60 are 2 x 2 x 3 x 5
and multiple of 6 = 6, 12, 18, 24, 30, ..........
factors of 60 can also be written as
2 x 5 x 6
5 x 12
2 x 30, all these are factors of 60
form factors, we find that 6, 12, and 30 are factors and multiple of 6 in different forms.
Hence the numbers 6, 12, and 30 are factors of 60 and multiple of 6 in a different form of factors.
