Answer:

21

Step-by-step explanation:

it is not a prime number, according to prime number only the number and 1 can it be divided but here 21 can be divided by 1,3,7 and 21 itself. Therefore others are prime number except 21

Answer:

Hexagons, Cross sections parallel to the base will be hexagons. It is also possible to take cross sections using planes that are neither parallel not perpendicular to the base

Answer:

The cross-section parallel to the base is a hexagon congruent to the hexagonal bases. The cross-section perpendicular to the base is a rectangle. The cross-section parallel to the base is a pentagon similar to the pentagonal base. The solid is a cylinder.

Answer:

im good

Step-by-step explanation:

The easiest and most time-effective way to approach this problem is to use the quadratic formula:

[tex]x=\frac{-b\pm\sqrt{ b^2-4ac}}{2a}[/tex],

where a = 2, b = -1, and c = 4. (We get this from the general quadratic: ax² + bx + c.)

When we plug in our numbers, we get [tex]x=\frac{1\pm\sqrt{1-32}}{4}[/tex] which also equals [tex]\frac{1\pm i\sqrt{31}}{4}[/tex], or the first choice!

Answer:

B=.5*8*6=.5*48=24

h = 8

P=10+6+8=24

Surface area =2*24+24*8=48+192=240

Step-by-step explanation:

The base is a triangle, and the area of a triangle is 1/2 base (or width) times height (or length). In this case, base is 8 and height is 6, so the area can be found either by multiplying .5*8*6 or by dividing 8*6 by 2, either of which will give you the same answer of B=24.

Height is given, h=8.

Perimeter is simply the sum of the sides, which are given, so the perimeter is 8+6+10=24.

The formula for surface area is given, so all you need to do is plug in your previous answers and you've got it!

The quotient is 2

Answer:

Step-by-step explanation:

The diagram is given to you below. I could not change <C so that it was theta. So C = theta.

So C is the reference angle. Call it theta when you think of it. The diagram shows you how cos(C) must be set up.

The adjacent side is 7

The hypotenuse is 18

theta = C = cos-1(7/18) = 67.11

To the nearest degree 67.11 = 67

The length of a rectangle if the length is I = 2w + 1.

A Rectangle is a 4 sided-polygon, having all the inner angles identical to 90 ranges. the 2 aspects at each corner or vertex, meet at right angles. the alternative sides of the rectangle are identical in length which makes it specific from a square.

The area of the rectangle is = length * breath

The perimeter of the rectangle = 2(L*B)

Answer:

3 (3a-6b+7c)

Step-by-step explanation:

Answer:

Step-by-step explanation:

The highest common factor is 3.

9/3 = 3

18/3 =6

21/3 = 7

The literals have no common factors that we know of.

Answer: 3(3a - 6b + 7c)

Answer:

m=5/3

Step-by-step explanation:

Answer:

5/3 or 1 2/3

Step-by-step explanation:

First you subtract 4/3 from the left side. 23/6-4/3= 2 1/2

Then you multiply 2 on both sides, this simplifies the left side to be 3m and the right side 5.

Lastly, you divide by 3 to isolate the variable m.

And you get 5/3, which also equals 1 2/3

Step-by-step explanation:

-8 - x =-5

Answer:

x=0

Step-by-step explanation:

- 7(x + 4) - 4= - 32

Add 4 to each side

- 7(x + 4) - 4+4= - 32+4

- 7(x + 4) = - 28

Divide by -7

- 7(x + 4) /-7= - 28/-7

x+4 = 4

Subtract 4 from each side

x+4-4 = 4-4

x=0

Part 1

[tex]\left(\frac{g}{h}\right)(x) = \frac{g(x)}{h(x)}\\\\\left(\frac{g}{h}\right)(x) = \frac{3x-5}{-2x^2+7}\\\\\left(\frac{g}{h}\right)(3) = \frac{3(3)-5}{-2(3)^2+7}\\\\\left(\frac{g}{h}\right)(3) = \frac{4}{-11}\\\\\left(\frac{g}{h}\right)(3) = -\frac{4}{11}\\\\[/tex]

Answer:  -4/11

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

Part 2

Set the denominator function equal to zero and solve for x to find which values to kick out of the domain.

[tex]h(x) = 0\\\\-2x^2+7 = 0\\\\7 = 2x^2\\\\2x^2 = 7\\\\x^2 = 7/2\\\\x^2 = 3.5\\\\x = \sqrt{3.5} \ \text{ or } x = -\sqrt{3.5}\\\\[/tex]

This shows that if x is equal to either of those values, then the denominator h(x) will be zero. These are the values to kick out of the domain to prevent a division by zero error. Any other value of x is valid in the domain.

Answer: [tex]x = \sqrt{3.5} \text{ and } x = -\sqrt{3.5}\\\\[/tex]
