PLS EXPLAIN I NEED HELP
bearhunter [10]

Answer: x = 20 units

Step-by-step explanation:

     Since this is a right triangle, we can use the Pythagorean theorem (c is the hypotenuse and a & b are the legs.);

           a² + b² = c²

a² + b² = c²

(21)² + (x)² = (29)²

441 + (x)² = 841

(x)² = 400

x = \sqrt{40} = 20

0.039 in scientific notation
Zielflug [23.3K]

Answer:

3.9 * 10^-2

Step-by-step explanation:

We need a number between 0 and 10, so we need to multiply.

0.039 * 10 = 0.39

0.39 * 10 = 3.9

Since 0.039 is less than 0, we are going to have a negative exponent.

3.9 * 10^-2

Best of Luck!

Eddi Din [679]

Answer:

The answer to your question is    4x¹¹\sqrt{5}

Step-by-step explanation:

Expression

                              2x\sqrt{20x^{20}}

Process

1.- Find the prime factors of 20

                   20  2

                    10  2

                     5  5

                     1

    20 = 2²5

2.- Express the square root as a fractional exponent

                             2x2²/²5¹/² x²⁰/²

3.- Simplification

                             2x¹(2)(5¹/²)(x¹⁰)

                             4x¹¹5¹/²

                             4x¹¹\sqrt{5}

4.- Conclusion

None of your answer, because we must consider \sqrt{5}.
