PLEASE HELPP … Find the measure of BD .
postnew [5]

Answer:

BD = 8.5 units

Step-by-step explanation:

From the figure attached,

ΔABC and ΔADB are the right triangles.

By applying mean proportional theorem,

\frac{\text{AD}}{\text{BD}}=\frac{\text{BD}}{\text{CD}}

BD² = AD × CD

BD² = 6 × 12

BD = √72

BD = 6√2

     = 8.485

BD ≈ 8.5 units

Therefore, measure of segment BD will be 8.5 units.

Answer:

25n

Step-by-step explanation:

It gives us the answer, we just have to simplify it. The problem says that "5n + 20n shows the total amount of money" and we are <em>looking</em> for an expression that shows the total amount of money.

5n + 20n = 25n

Have a nice day!

     I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
