x^2 = 16/100
We must solve for x by taking the square root of both sides.
But imagine x^2 = 9. x = 3 is a solution because 3^2 = 9. But x = -3 is also a solution because (-3)^2 = 9. So we need to add the plus and minus sign to account for all of our solutions.
√x^2 = √(16/100)
We square root both sides to remove the exponent 2 on x. Then
x = ±√(16/100)
Then we have to use a Property of Radicals which is √(x/y) = √(x) / √(y).
Then the square root of 16 is 4 and the square root of 100 is 10. 4/10 is 2/5 simplified.
0 is the answer of questions

Answer:
Well 1 centimeter is 10 millimeters.
260000 mm divided by 10 is 26000
so 26000 centimeters
Identify first the common difference of the arithmetic sequence by the following,
d = (a22 - a1) / 22 - 1
d = (-226 - 26) / 22 -1 = -12
Solving for the 31st term,
a31 = a1 + (n - 1)d
a 31 = 26 + (31 - 1)(-12)
a 31 = -334
Therefore, the answer is letter A. -334.
