Answer:

  m = 4√6

Step-by-step explanation:

Using the "geometric mean" relations applicable to this triangle, the value of m is the geometric mean of the hypotenuse segments it touches:

  m = √((8)(8+4)) = √96

  m = 4√6

__

Additional comment

Similarly, n = √(4×8) = 4√2.

These relations come from the similarity of the triangles. For m, the proportion is ...

  long side/hypotenuse = 8/m = m/12

  96 = m²   ⇒   m = 4√6

Answer:

  2x -16

Step-by-step explanation:

The area of each rectangle is the product of its length and width. The shaded area is the difference between the areas of the outside rectangle and the inside rectangle.

  shaded area = (2x -1)(x +6) -(2x +5)(x +2)

  = (2x^2 +11x -6) -(2x^2 +9x +10)

  = (2 -2)x^2 +(11 -9)x +(-6 -10)

  = 2x -16 . . . . . area of the shaded region

Trinomial is the polynomial in which the highest power of the unknown variable is 3.

The factor of a polynomial is the terms in linear form, which are, when multiplied together, give the original polynomial equation as a result.

The model of a trinomial is shown. An algebra tile configuration. 0 tiles are in the Factor 1 spot and 0 tiles are in the Factor 2 spot.

24 tiles are in the Product spot: 1 is labeled x squared, 7 Thus, one of the factor of trinomial is,

[tex](x-7)[/tex]

The 2 tiles below x squared are labeled x, and the 14 tiles below the negative x tiles are labeled negative. Thus, the another factor of the trinomial is,

Step-by-step explanation:

$3.75/3x + $1.50y = $15.50

So, if you have 4 protein bars, the equation would read:

1.25x + 1.5y = 15.5

1.25(4) + 1.5y = 15.5

5 + 1.5y = 15.5

1.5y = 10.5

y = 7

Answer:

the first option is correct

In a function, y varies directly with x and the constant variation is 2, then the function is y=2x. Therefore, option D is the correct answer.

Mathematical relationship between two variables which can be expressed by an equation in which one variable is equal to a constant times the other.

Given that, in a function, y varies directly with x and the constant variation is 2.

y∝x

y=kx, where k is constant variation.

Here, k=2

Then, y=2x

When x=1, 2, 3, 4 and 5.

We get, y 2, 4, 6, 8 and 10

Therefore, option D is the correct answer.

The slope of AB is different from the slope of BC

==================================================

Reason:

Points A,B,C are all on the same line. We consider them collinear points. This means that the slopes of AB, AC and BC are the same value.

If the slopes were different at all, then the points wouldn't be collinear. In this case, the slope is 2/3 because we move up 2 each time we move to the right 3 units.

Step-by-step explanation:

[tex]6x^{2} -4xy + 2y^{2} -5x^{2} +2xy+10xy[/tex]

Okay, so of course you need to add like terms. But where should you start? Well, [tex]6x^{2}[/tex] and [tex]-5x^{2}[/tex] are both like terms, so lets add them first.

[tex]6x^{2} -5x^{2} = x^{2}[/tex]

Also, [tex]-4xy[/tex], [tex]2xy[/tex], and [tex]10xy[/tex] are like terms, so we can add them together too.

[tex]-4xy + 2xy +10xy = 8xy[/tex]

There isn't anymore like terms, so now we need to put it in simplest form.

[tex]x^{2} +2y^{2} +8xy[/tex]

Hope this helps! I actually think 2y^2 is before x^2 in the answer, but unless you need it in simplest form it shouldn't matter. Review with your teacher before turning in if you can. :))

Answer:

m∠4 = 140°

Step-by-step explanation:

m∠1 = m∠4  (parallel lines with same angle)

m∠2 = m∠3  (parallel lines with same angle)

if m∠2 = m∠3 are equal:

3x + 10 = 5x - 10

3x - 5x = -10 - 10

-2x = -20

x = 10°

m∠2 = m∠3 = 3x + 10 = 3(10) + 10 = 40°

m∠1 + m∠4 + 40° + 40° = 360°

2 m∠4 = 360° - 80°

2 m∠4 = 280°

m∠4 = 140°

Answer:

m∠4 = 140°

Step-by-step explanation:

Vertical Angle Theorem: vertical angles are always congruent.

Therefore, m∠1 = m∠4  and  m∠2 = m∠3

As m∠2 = m∠3, then

⇒ 3x + 10 = 5x - 10

⇒ 20 = 2x

⇒ x = 10

So m∠2 = 3x + 10 = 3(10) + 10 = 40°

m∠2 and m∠4 form a linear pair

Therefore m∠2 + m∠4 = 180°

⇒ 40 + m∠4 = 180

⇒ m∠4 = 140°

Linear pair: a pair of adjacent angles formed when two lines intersect.  The two angles of a linear pair always sum to 180°
