Answer:

Step-by-step explanation:

By the diagram, you can see the sum of segment AB and segment BC is segment AC. Adding the given expressions for AB and B is $3x-6$ . Simplifying the equation $3x-6=2x+1$ , gives $x=7$ . Substituting $x=7$ in the equation for segment AC gives 15.

Simplify. 5√ 10 <br> 1) 2√ 2) 2√2 3) 10√2 4) 5√

Nataly_w [17]

For this case we have that the expression in its exact form is the same, that is:

$5 \sqrt {10}$

If it is expressed in decimal form we have:

$5 \sqrt {10} = 1.5849$

If we want equivalent expressions, we must first mention the following property of powers and roots:

$\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}$

Then, we can rewrite the expression as:

$5 \sqrt {10} = \sqrt {5 ^ 2 * 10} = \sqrt {25 * 10} = \sqrt {250}$

Answer:

$5 \sqrt {10} = \sqrt {250} = 1.5849$
