Ineed to know the answer for 15, if you can show your work

The answer is: D. 6.9 x 10^5

Step-by-step explanation:

To find the answer, you simply need to convert the scientific notation into normal notation and then divide the largest value by the smallest value.

Scientific Notation             Normal Notation

3.45 E 9                              3,450,000,000

0.5 E 4                                5000

Divide these values and you get:

690,000

or

6.9 E 5

x = 17

step-by-step explanation:

in the given figure, two triangles are inscribed in a circle where ∠bae ≅ ∠dae which makes the side be and de equal so we can write it as:

3x - 24 = x + 10

solving this equation for x to get:

3x - x = 10 + 24

2x = 34

x = 34/2

x = 17

therefore, the value of x = 17.

it would be 6xy and -16xy.
