I believe there is a typo in the problem. It should be:<span>1.8, 2.85, 3.90, 4.95, 6
If that was the case, the answer will be easy.

In this sequence, the rule is start at 1.80 then keep add 1.05. You can try to put them all into the equation

</span>1.80 + 1.05= 2.85
2.85+ 1.05= 3.90
3.90+ 1.05= 4.95
4.95+ 1.05= 6.00

What is the solution to the inequality 3-|4-n|>1? no solution all real numbers n > 2 or n < 6 2 < n < 6

Ket [755]

3-|4-n|>1
3-3 -|4-n| > 1-3
-|4-n| > -2
-|4-n|/-1 > -2/-1
|4-n| < 2
**inequality flips when dividing by a negative, absolute values give 2 answers
4-n <2
or
4-n >-2
n > 2. or. n < 6
2 < n < 6

<h2><u>Q</u><u>u</u><u>e</u><u>s</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

If a = 6 - $\sqrt{35}$ , find the value of a² + $\frac{1}{a²}$

<h2><u>S</u><u>o</u><u>l</u><u>u</u><u>t</u><u>i</u><u>o</u><u>n</u>:-</h2>

a = 6 - $\sqrt{35}$ (Given)

Now, first of all we have to find the value of $\frac{1}{a}$ .

So, $\frac{1}{a}$ = $\frac{1}{6 \: - \: \sqrt{35}}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{(6 \: - \: \sqrt{35})(6 \: + \: \sqrt{35})}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{(6)² \: - \: (\sqrt{35})²}$

$\frac{1}{a}$ = $\frac{6 \: + \sqrt{35}}{36 \: - \: 35}$ $(\because \sqrt{35} \: × \: \sqrt{35} \: = \: 35)$

$\frac{1}{a}$ = $\frac{6 \: + \: \sqrt{35}}{1}$

$\frac{1}{a}$ = 6 + $\sqrt{35}$

Now, we have to find the value of a² + $\frac{1}{a²}$

So, a² + $\frac{1}{a²}$ = $(a \: + \frac{1}{a})²$ - 2.a. $\frac{1}{a}$

a² + $\frac{1}{a²}$ = $(6 \: - \sqrt{35} \: + \: 6 \: + \sqrt{35})²$ - 2

a² + $\frac{1}{a²}$ = (12)² - 2

a² + $\frac{1}{a²}$ = 144 - 2

a² + $\frac{1}{a²}$ = 142

The value of a² + $\frac{1}{a²}$ is <u>1</u><u>4</u><u>2</u>. [Answer]

What is the simplified form of each expression?

White raven [17]

<h2>~<u>Solution</u> :-</h2>

According to the given question, we have to find the simplified form of the given expressions. Here, we have been given;

<h3>★ <u>Equation</u> 1 :-</h3>

$\sf{(6 + 3)2 - 4}$

$\leadsto \sf{(9)2 - 4}$

$\leadsto \sf{18 - 4}$

$\leadsto \bf \red{14}$

Hence, (6 + 3)2 - 4 is equals to 14.

$\\$

<h3>★ <u>Equation</u> 2 :-</h3>

$\sf{23 + (14 - 4) \div 2}$

$\leadsto \sf{23 + (10) \div 2}$

$\leadsto \sf{23 + 5}$

$\leadsto \bf \red{28}$

Hence, 23 + (14 - 4) ÷ 2 is equals to 28.
