The area of a square can be represented by the expression x^10. Which monorail represents a side of a square

Mathematics
1 answer:
suter [353]3 years ago
4 0

Answer:

The length of the side of a square is \mathbf{x^5}

Step-by-step explanation:

Area of square = x^{10}

We need to find length of the side

The formula used will be:

Area\:of\:square=(length)^2

Putting value of area of square, we can find length

Area\:of\:square=(length)^2\\x^{10}=(length)^2\\Switching\:sides\\(length)^2=x^{10}\\Taking\:square\:root\:on\:both\:sides\\\sqrt{(length)^2}=\sqrt{x^{10}}\\(length)^{\frac{2}{3} }=x^{\frac{10}{2}} \\length=x^5

So, length of the side of a square is \mathbf{x^5}

Answer:

B. 1.-1,-2

Step-by-step explanation:

g(x) = x ^{3}  + 2 {x}^{2}  - x - 2

Substitute g(x)=0

0 =  {x}^{3}  + 2 {x}^{2}  - x - 2

Move the expression to the left

0 - {x}^{3}  - 2 {x}^{2}  + x + 2 = 0

Factor out -x^2 from the expression

-  {x}^{2}  \times (x + 2) + x + 2 = 0

Factor out (x+2) from the expression

(x + 2) \times ({x}^{2}  + 1) = 0

When the product of the factor equals 0, at least one factor is 0

x + 2 = 0

- {x}^{2}+ 1 > = 0

Solve for x

x =  - 2 \\ x =  - 1\\ x = 1

A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees. How many tick
Citrus2011 [14]

Answer:

As per the statement: A radio station had 205 tickets to a concert. They gave away 4 times as many tickets to listeners as to employees.

⇒Let number of tickets Employees have x and Number of ticket Listeners  have 4x

It is also, given that a radio station had 205 ticket to a concert.

⇒ \text{Number of ticket Employees have} +\text{Number of ticket Listeners have} = 205

Then, substitute the given values we have;

4x + x = 205

Combine like terms, we have;

5x = 205

Divide both sides by 5 we have;

x = 41

Therefore, number of tickets did they give away to employees have 41 tickets

Find the value of x.<br> (7x - 1)º<br> (6x - 1)º
dangina [55]

Answer:

Step-by-step explanation:

7x - 1 + 6x - 1 = 180

13x - 2 = 180

13x = 182

x = 14

7(14) - 1 = 98 - 1= 97

6(14) - 1 = 84 - 1 = 83

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

y = -4x + 1

11y = x + 146

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                  11(-4x + 1) = x + 146
  2. Distribute 11:                                                                                                      -44x + 11 = x + 146
  3. [Addition Property of Equality] Add 44x on both sides:                                11 = 45x + 146
  4. [Subtraction Property of Equality] Subtract 146 on both sides:                      -135 = 45x
  5. [Division Property of Equality] Divide 45 on both sides:                              -3 = x
  6. Rewrite/Rearrange:                                                                                          x = -3

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define original equation:                                                                                 y = -4x + 1
  2. Substitute in <em>x</em>:                                                                                                 y = -4(-3) + 1
  3. Multiply:                                                                                                           y = 12 + 1
  4. Add:                                                                                                                    y = 13
