What is the value of X enter your answer in the box

Mathematics
1 answer:
stealth61 [152]3 years ago
4 0

Answer:

Step-by-step explanation:

Set up the following ratio which applies to all angle bisectors  and the side opposite.

8 / (x + 4) = 12 / (2x + 1)                Cross multiply

8 * (2x + 1) = 12 * (x + 4)

16x + 8 = 12x + 48                        Subtract 8 from both sides

16x + 8 -8 = 12x + 48-8

16x = 12x + 40                              Subtract 12x from both sides

16x - 12x = 40

4x = 40                                         Divide by 4

4x/4 = 40/4

x = 10

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second.
Norma-Jean [14]

Answer:

1

Step-by-step explanation:

What is the largest of 3 consecutive integers such that the sum of the first and third is equal to three times the second?

3 consecutive angles

= x, x + 1, x + 2

We are told in the question that:

the sum of the first and third is equal to three times the second

a + c = 3b

x + x + 2 = 3(x + 1)

2x + 2 = 3x + 3

3x - 2x = 2 - 3

x = -1

The largest of the three numbers is the third number

= x + 2

x = -1

x + 2 = -1 + 2

The third and largest number is 1

What algebraic rule did you use to preform this<br> translation????
Law Incorporation [45]

Answer:

In geometry, a transformation is an operation that moves, flips, or changes a shape (called the preimage) to create a

new shape (called the image). A translation is a type of transformation that moves each point in a figure the same

distance in the same direction. Translations are often referred to as slides. You can describe a translation using words

like "moved up 3 and over 5 to the left" or with notation. There are two types of notation to know.

1. One notation looks like T(3, 5). This notation tells you to add 3 to the x values and add 5 to the y values.

2. The second notation is a mapping rule of the form (x, y) → (x−7, y+5). This notation tells you that the x and

y coordinates are translated to x−7 and y+5.

The length, in millimeters of each side of a square shaped electronic chip is a rational number. What statement is true about th
AVprozaik [17]

Answer:

The diagonal is irrational because it is a product of a rational and an irrational number

Step-by-step explanation:

The options are not given. However, the question is still answerable.

Given

Shape: Square

Length: Rational

Since the side length is said to be rational, I'll answer the question based on whether the diagonal is rational or not.

Having said that:

The diagonal (d) of a square with side length (l) is calculated using Pythagoras theorem.

d^2 = l^2 + l^2

d^2 = 2l^2

Take positive square root of both sides

d = \sqrt{2l^2}

Split:

d = \sqrt{2} * \sqrt{l^2}

d = \sqrt{2} *l

Recall that the side length (l) is rational.

However, \sqrt 2 is irrational.

So, the product of l and \sqrt 2 will be irrational

Hence:

The diagonal is irrational
