We are given the expression of square root of one over 121 and is asked to simplify the expression. Simply, to answer this question, we take the square root of each number. square root of 1 is 1 while the square root of 121 is 11. Hence the simplified expression becomes 1/11.

Answer:

\frac{1}{11}

Step-by-step explanation:

\sqrt{\frac{1}{121} }

To simplify the square root we take square root at the top and bottom separately.

\sqrt{\frac{1}{121} }

\frac{\sqrt{1}}{\sqrt{121}}

square root (1)=1

square root of 121 is 11

So the fraction becomes

\frac{\sqrt{1}}{\sqrt{121}}

\frac{1}{11}

vesna_86 [32]

Answer:

see explanation

Step-by-step explanation:

In 13 - 17

Consider the factors of the constant term which sum to give the coefficient of the x- term

13

x² - x - 42 = (x - 7)(x + 6)

15

x² + x - 6 = (x + 3)(x - 2)

17

x² - 27x + 50 = (x - 25)(x - 2)

19

r² - 25 ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , thus

r² - 25

= r² - 5² = (r - 5)(r + 5)

Trava [24]

Answer:

12 inches

Step-by-step explanation:

30-13=17

17-5= 12

Use information about the triangle's perimeter, to find the side length of C.

If the triangle frame is a right triangle, than you could use the Pythagorean Theorem and use the following formula, a^2 + b^2 = c^2, to find the measure of side c.

Have a great rest of your day, and I hope this helps!
