Answer:

4x^{5}

Step-by-step explanation:

The given expression is 4\sqrt{x^{10}}

We have to simplify the given expression

4\sqrt{x^{10}}=4\sqrt{(x)^{5}(x)^{5}}

= 4\sqrt{(x^{5})^{2}}

= 4[(x^{5})^{2}]^{\frac{1}{2}}

= [(x^{5})^{2\times \frac{1}{2}}] [Since [a^{m}]^{n}=a^{m\times n}

= 4x^{5}

Therefore, the expression equivalent to the given expression will be 4x^{5}

Is the formula s=(n-2)180
Phantasy [73]

Answer:

Number of sides of the polygon

Step-by-step explanation:

The formula S=(n-2)180 is the sum of the measures of interior angles. So that's what S stands for. The only other variable remaining is n which is the number of sides of the polygon.

There's nothing I can do to help you understand this, you just have to memorize it.

Which expression is not equivalent to the other three?
AVprozaik [17]

Answer:

<em>4 + 7x – 2</em>

Step-by-step explanation:

<u>Equivalent Expressions</u>

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

2x + 2+ 2x + 3x -8=7x-6

Now for the second expression

4 + 7x -2=7x+2

The third expression simplifies to

-2 + 5x + 2x - 4=7x-6

Finally, this is the simplification for the expression

8x - x - 6=7x-6

As seen, the only expression not equivalent to the other three is 4 + 7x – 2

The value of the angle m∠4 is 105 degrees.

<h3>How to find angles in a quadrilateral?</h3>

The sum of angles in a quadrilateral is 360 degrees.

Therefore,

m∠1 + m∠2  + m∠3 + m∠4 = 360°

Hence,

x + x + 10 + x + 20 + x + 30 = 360

4x + 60 = 360

4x = 360 - 60

4x = 300

x = 360 / 4

x = 75

Therefore,

m∠4 = 75 + 30 = 105°
