\sqrt(x^(2)-14x+49)=x-7

Answers

Answer:

infinite solutions

Step-by-step explanation:

note the expression inside the radical is a perfect square, that is

x² - 14x + 49 = (x - 7)², then

[tex]\sqrt{x^2-14x+49}[/tex] = x - 7

[tex]\sqrt{(x-7)^2}[/tex] = x- 7, that is

x - 7 = x - 7

Since both sides are the same then any value of x will make the equation true.

The equation has infinite solutions

Step-by-step explanation:

Answer:

43 Degrees

Step-by-step explanation:

(3x + 16) + (6x + 1) + (82) = 180 Degrees

180 - 82 = 98 Degrees

(3x + 16) + (6x + 1) = 9x + 17

9x + 17 = 98

98 - 17 = 81

81 / 9 = 9

x = 9

6(9) + 1 = 55 Degrees

3(9) + 16 = 43 Degrees

55 + 43 + 82 = 180 Degrees

Please really need help it’s for a test

Answers

Answer:

BC = 10.9 mm

Step-by-step explanation:

The computation of the BC is given below:

Here we applied the pythagorus theorem

AB = 10.8 mm

AC = 1.6mm

BC = ?

Now as we know that

AB^2 + AC^2 = BC^2

10.8mm^2 + 1.6mm^2 = BC^2

116.64mm^2 + 2.56mm^2 = BC^2

BC = 10.9 mm

Its mathematics.

Answers

Answer:

The height is 15 cm. The volume is 6000 cm³

Step-by-step explanation:

The base is square, so the sides are equal.

√400 = 20. This is the length and width of the cuboid.

The area of the base and the area of the top face are equal, so we subtract 2(400) from the total area to get the area of the remaining 4 faces.

2000 - 800 = 1200 cm²

Divide by 4 to get the area of an individual face.

1200/4 = 300 cm²

We found the width earlier: 20cm

We found the width earlier: 20cm300/20 = 15cm. This is the height.

To find Volume, multiply Area of the base times the height:

400cm²×15cm = 6000cm³

So, lets use it to find the hypotenuse-

5²+12²=c²

(5*5)+(12*12)=(c*c)

Match each irrational number line on which it is represented 2.18112... 2.1823912 2.364125 2.1829391321

Answers

Answer:

See Explanation

Step-by-step explanation:

The number lines to make selection from are missing from the question.

However, I've attached 4 number lines, each of which represents each of the given irrational numbers (see attachment)

Number: 2.1823912

This is represented by number line 1

Each point of number line 3 is 0.001 units starting from 2.18;

The point which the red dot is located is between 2.182 and 2.183, but the dot is closer to 2.182.

2.1823912 and 2.1829391321 satisfy this property but number line 2 represents 2.1829391321 (see below for explanation)

So: 2.1823912 is represented by number line 1

Number: 2.1829391321

This is represented by number line 2.

Each point of number line 3 is 0.0001 units starting from 2.182;

The point which the red dot is located is between 2.1829 and 2.1830, but the dot is closer to 2.1829.

From the list of given numbers, only 2.1829391321 satisfy this property.

Number: 2.18112...

This is represented by number line 3.

Each point of number line 3 is 0.01 units starting from 2.11;

The point which the red dot is located is between 2.18 and 2.19.

If number lines 1 and 2 represent 2.1823912 and 2.1829391321, respectively, then number line 3 represents 2.18112.

Number: 2.364125

This is represented by number line 4.

Each point on this number line is 0.1 unit starting from 2.0;

The point which the red dot is located is between 2.30 and 2.40. From the list of given numbers, only 2.364125  satisfy this property.

Answer:

1: 2.1823912 2: 2.364125 3: 2.18112 4: 2.18929391321

Step-by-step explanation:

5x - 4 = 41

add

5x = 45

divide

x = 9

Answer:

x = 9

Step-by-step explanation:

First, add 4 to both sides.

5x - 4 + 4 = 5x (+4 and -4 cancel one another out, leaving just 5x)

41 + 4 = 45

So, we get 5x = 45

Divide by 5 on both sides.

5x/5 = x (Again, 5 is cancelled out)

45/5 = 9

We get x = 9
