Answer:

40 units

Step-by-step explanation:

If two secants are drawn to a circle from one exterior point, then the product of the external segment and the total length of each secant are equal.

Thus,

AC\cdot AE=AB\cdot AD.

Since AD=8 units, AE=6 units , EC=12+BD units, then

AC=AE+EC=6+12+BD=18+BD\ units,

AB=AD+DB=8+BD\ units.

Therefore,

(18+BD)\cdot 6=(8+BD)\cdot 8,\\ \\108+6BD=64+8BD,\\ \\2BD=44,\\ \\BD=22\ units

and

AC=18+22=40\ units.

Setler [38]

Answer:

Place value is the value of each digit in a number. For example, the 5 in 350 represents 5 tens,When rounding an integer, all place values to the right of the rounding position are filled with zeros. For example, let's round 8,372 to the hundreds position, which currently contains the number 3. Because the number following the 3 is a 7, we raise the 3 to a 4, and the answer is 8,400.
