Answer:

monitta3 years ago
3 0

Answer:

The answer is \frac{2x}{15}

First, you have to have both fractions have the same denominators. With that, you can subtract both with them.

So, the LCD (Lowest common denominator) is 15, meaning, you have to multiply both fractions to get the denominator to 15.

Multiply 4x/5 by 3 (both numerator and denominator) and multiply 2x/3 by 5 (both n and d).

After multiplying, you get 12x/15 - 10x/3

Then you subtract it and get 2x/15 !

Answer:

x = √30

Step-by-step explanation:

From small triangle BDC:

using Pythagorean theorem

CB² = BD² + DC²

x² = BD² + 3²

Fron triangles BDC and ADB.

ΔBDC has long leg BD and short leg DC.

ΔADB has long leg AD and shirt leg BD.

AD : BD = BD : DC

7 : BD = BD : 3

7*3 = BD*BD

BD² = 7*3 = 21

x² =  BD² + 3² = 21+9 = 30

x² = 30

x = √30
