Answer:

a.)

Step-by-step explanation:

(\sqrt{12}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form for \sqrt{12}:

Find two numbers that multiply to 12, one of which is a perfect square:

\sqrt{12}=\sqrt{3*4}

Separate:

\sqrt{3}\sqrt{4}

Simplify by finding the square root:

\sqrt{3}*2=2\sqrt{3}

Insert the simplified version:

(2\sqrt{3}+6)(-\sqrt{8}-\sqrt{2})

Find the simplest radical form of \sqrt{8}:

Find two numbers that multiply to 8, one of which is a perfect square:

\sqrt{8}=\sqrt{4*2}

Separate:

\sqrt{4} \sqrt{2}

Simplify by finding the square root:

2\sqrt{2}

Insert the simplified version:

(2\sqrt{3}+6)(- 2\sqrt{2}-\sqrt{2})

a number with 2 consecutive natural digits, how many units will it increase if written in reverse order. Detail solution pls
svetlana [45]

Answer:

It will increase by 9 units.

Step-by-step explanation:

We can write the lowest number as  10a + (a + 1) and the highest is the reverse which is 10(a + 1) + a.

Subtracting:

10(a + 1) + a - (10a + a +1)

= 10a + 10 + a - 10a - a - 1

= 10a - 10a + a - a + 10 - 1

= 10 - 1

= 9.
