The rational number among all the answer choices is; Pi + √16.

A rational number by definition, is one that can be represented as the quotient a/b of two integers in which case b ≠ 0.

On this note, it follows that since the constant pi is; 22/7, the number pi + √16 can be represented as a rational number as follows;

The value of P is 50 degree , Option D is the correct answer.

According to the exterior angle property the measure of exterior angle is equal to the sum of opposite interior angles.

In the given figure it can be seen that one of the exterior angle is 90 degree ,

which is making a supplementary angle with the interior angle corresponding to it , angle B in the figure

Therefore the interior angle B is 90 degree ,

The value of angle C = p degree

To determine the value of angle C

The exterior angle next to angle A = 140 degree

By the exterior angle property

140 = 90 +p

p = 50 degree

The value of P is 50 degree , Option D is the correct answer.

Answer:

x = 65 , y = 64

Step-by-step explanation:

y - 16 and 2y + 4 are same- side interior angles and sum to 180° , that is

y - 16 + 2y + 4 = 180

3y - 12 = 180 ( add 12 to both sides )

3y = 192 ( divide both sides by 3 )

y = 64

then

2y + 4 = 2(64) + 4 = 128 + 4 = 132

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

2y + 4 is an exterior angle of the triangle , then

x + 67 = 132 ( subtract 67 from both sides )

x = 65

Answer:

2q+6

Step-by-step explanation:

So basically, you would do this.

-2q-6+6q+12-2q

Next

-4q+6q = 2q

12-6=6

2q+6

Answer:

2q + 6

Step-by-step explanation:

To simplify, we will use the distributive property.

-(2q + 6) simplifies to -2q - 6 (In this case we are distributing the - sign or -1)

3(2q + 4) simplifies to 6q + 12

So if we recombine: -2q - 6 + 6q + 12 - 2q

Let's combine like terms (q's with q's, numbers with numbers)

-2q + -2q + 6q = 2q

-6 + 12 = 6

So if we recombine: 2q + 6

The solutions of the equation x² – 5x – 24 = 0 will be 8 and -3. Then the correct option is D.

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The quadratic equation is given below.

x² – 5x – 24 = 0

Then the factor of the equation will be

       x² – 5x – 24 = 0

x² – 8x + 3x – 24 = 0

x(x – 8) + 3(x – 8) = 0

Answer:

x = 59°, y = 31°

Explanation:

Angles (x) and (x - 28) sum ups to 90° on a straight line.

→ x + (x - 28) = 90

→ 2x - 28 = 90

→ 2x = 90 + 28

→ 2x = 118

→ x = 59°

Then find value of y

Angle y, x, 90° lies on a straight line which sum ups to 180°

→ x + y + 90° = 180°

→ 59 + y + 90° = 180°

→ y = 180° - 149°

→ y = 31°

The prove that the angle ABCD is said to be a parallelogram that shows both pairs of opposite sides as parallel figure is given below.

The four points in the shape above are : A, B, C, D.

Where

A = (-2,-4)

B = (1,2)

C = (2,10)

D = (-1,4)

We place or sit vector AB with vector DC and vector AD  with vector BC

and so we find and place their coordinates.

vector AB (1-(-2), 2-(-4))

vector DC (2-(-1),10-4)

vector AD (-1-(-2), 4-(-4))

vector BC (2-1,10-2)

So we obtained:

vector AB (3,6)

vector DC (3,6)

vector AD (1,8)

vector BC  (1,8)

Next step is to calculate for the lengths :

AB=   [tex]\sqrt{3^{2} + 6^{2} }[/tex]  DC= [tex]\sqrt{3^{2} + 6^{2} }[/tex]

Thus, AB = DC

AD = [tex]\sqrt{1^{2} + 8^{2} }[/tex]     BC =[tex]\sqrt{1^{2} + 8^{2} }[/tex]

Hence one can say that  AD is equal to  BC.
