Pls answer this qn i need it urgently

Elis [28]

Answer:

First rationalize the surd

(√3 +√2)(√3 - √2)/(√3 - √2)(√3 -√2)

The final answer will be 5 + 2√6

So x = 5 + 2√6

I) x + 1/x

5 + 2√6 + 1/5 + 2√6

Find the LCM

The final answer will be 10

ii) x² +1/x²

(5 + 2√6)² + 1/(5 +2√6)²

= 49 + 20√6 + 1/49 + 20√6

Find the LCM

The final answer will be 98

For i) x = 10

ii) x = 98

Hope this helps.

For parallelogram ABCD, what is the perimeter and measure of AC?

Mkey [24]

Perimeter = 68 Units

Answer:

AC = 30 Units

Step-by-step explanation:

The diagonals AC and BD of parallelogram ABCD are bisecting each other by making 90° angle, this tells us that it is a RHOMBUS.

All sides of rhombus are congruent.

AB = 17 units....(given)

Therefore,

Perimeter = 4*17 = 68 Units

Let diagonals AC and BD intersects at point O.

Therefore, by Pythagoras theorem:

$OA^2 = AB^2 - OB^2 \\ OA= \sqrt{AB^2 - OB^2 } \\ = \sqrt{ {17}^{2} - {8}^{2} } \\ = \sqrt{289 - 64} \\ = \sqrt{225} \\ = 15 \\ \because \: AC = 2\times OA \\ \therefore \: AC = 2\times 15 \\ \therefore \: AC = 30 \: units \\$
