Answer:

x = 2 or x = 3

Step-by-step explanation:

x = 2 + sqrt(x - 2)

x - 2 = sqrt(x - 2)                  You could divide both sides by sqrt(x - 2)

sqrt(x - 2) = 1                        Square both sides

x - 2 = 1                                Add 2 to both sides

x = 3

There is a second way.

x - 2 = sqrt(x - 2)                 Square

x^2 - 4x + 4 = x - 2             Transfer x - 2 to the left

x^2 - 5x + 6 = 0                   Factor

(x - 2)(x-3)      = 0                 Find the roots.

x - 2 = 0

x = 2

x - 3 = 0

x = 3

We have to check both results.

x = 2 + sqrt(x - 2)

2 = 2 + sqrt(2 -2)

2 = 2 + 0

2 = 2    This seems to work.

x = 2 + sqrt(x - 2)

3 = 2 + sqrt(3 - 2)

3 = 2 + sqrt(1)

3 = 2 + 1

3 = 3  And this works.

The surface area of the right prism cone is,

⇒ 1960 units²

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A right prism shown in image.

Now, We get;

Base area of cone = 14 x 10

                            = 140

And, Height of cone = 6

And, Perimeter of the base = 2 (10 + 14)

                                           = 280

Thus, WE know that;

The surface area of the right prism cone is,

⇒ 2B + hP

⇒ 2 × 140 + 6 × 280

⇒ 280 + 6 × 280

⇒ 280 + 1680

⇒ 1960 units²

Thus, The surface area of the right prism cone is,

⇒ 1960 units²

Well since a car can travel 78 miles Using 3 gallons

78/3=26

26 miles for each gallon

Answer:

26

Step-by-step explanation:

The unit rate refers to the distance the car can travel using 1 gallon of gas. One way to solve this is to create an algebraic equation like [tex]78=3x[/tex]. Then, to find the unit rate isolate x by dividing both sides by 3. This means that the unit rate is 26.

Your question is Incomplete....

Answer:

-x² + 6x - 17

Step-by-step explanation:

First, expand (x-3)² using FOIL

(x - 3)(x - 3)

= x² - 6x + 9

Distribute the negative sign to the expression:

-(x² - 6x + 9)

-x² + 6x - 9

Now, subtract 8 from this

-x² + 6x - 9

= -x² + 6x - 17

So, the equation in standard form is -x² + 6x - 17

The answer is.. x^2+6x-17

Ava makes bead necklaces. She has a total of 6048 beads. Each necklace has 24 beads. Her friend maria says that the greatest number of necklace she can make with the beads is 162. Marias. Work is shown here. Explain why Maria is incorrect and how she can find the correct answer.

Answer:

Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

Step-by-step explanation:

You can find the number of necklaces Avan can make by dividing the number of beads she has by the amount in each necklace:

6048/24=252

According to this, you can say that Maria is incorrect because when you divide the number of beads by the beads in each necklace, you find that she can make 252 necklaces.

Answer:1.75

Step-by-step explanation:

formula= R= D/2

x = -3 and x = 2

Step-by-step explanation:

The expression for the quadratic equation is as follows:

(x+3)(x-2)

For (x+3)(x-2) to equal 0, either (x+3) or (x-2) must be equal to 0. So,

(x+3) = 0 and (x-2) = 0

It implies,

x = -3 and x = 2

So, the values of x are -3 and 2.

Both (4, 1) and (5, 2) is the solution to the given equation. Therefore, option C is the correct answer.

The given equation is y+1=3(x-4).

A) The given coordinate point is (4, -1).

Substitute (x, y)=(4, -1) in y+1=3(x-4), we get

-1+1=3(4-4)

0=0

So, (4, -1) is the solution to the given equation.

B) The given coordinate point is (5, 2).

Substitute (x, y)=(5, 2) in y+1=3(x-4), we get

2+1=3(5-4)
