-5c+5c+2c–6c–16=c

-16c - 16=c

-16 = c + 16c

-16 = 17c

-16/17 = c

We have that

The  interval equivalent to each range is given below

[tex]x'=7,8,9 ...[/tex]

From the Question we are told that

2  <  x  ≤  5   or   x  >7

Generally the interval equivalent is given as follow from the number line

(...-1,0,1...)

For 2  <  x  ≤  5  

Here  this means x is less than 2 and less than or equal to 5

Therefore

A range of numbers

[tex]x=3-5[/tex]

For  x  >7

Here x is greater than 7  i.e

[tex]x'=7,8,9 ...[/tex]

in conclusion

The  interval equivalent to each range is given below

Answer:

P = 6x + 14

Step-by-step explanation:

P = 2l + 2w

where P is perimeter, l is length, and w is width

l = x + 7

w = 2x

So P = 2(x+7) + 2(2x)

Distribute the 2 to the x and 7.

P = 2*x + 2*7 + 2*2x

Multiply each term out

P = 2x + 14 + 4x

Group the xs

P = 2x + 4x + 14

Combine like terms

P = 6x + 14

D. Rational, integer, and whole.

Step-by-step explanation:

0 can be written in a ton of fraction forms (like [tex]\frac{0}{2645648}[/tex]), so it is rational.

Whole numbers include 0 and the natural numbers, but natural numbers alone, don't include 0.

Integers are the whole numbers and they negative opposites.

The point of tangency is the endpoint of either a radius or a diameter such that only one point of the circumference of the circle is concurrent with the endpoint of the diameter or radius of the circle.

Technically, it is none of them. E should be 180 degrees. That is really a sloppy question.

Answer:

84 cm squared, 30 cm squared, 18 cm squared

Step-by-step explanation:

Formula for triangle area= 1/2 Base * Height

Area for triangle ABD= 1/2 (12cm)*(14cm)

                                   =84 cm squared

Area for triangle BC(orange triangle)= 1/2 (6cm)*(10cm)

                                   =30 cm squared

BC=  half of BD

Area for triangle CD(Green  triangle)= 1/2 (6cm)*(4cm)

                                   =12 cm squared

area of green triangle is 12cm^2

Answer:

D.52

Step-by-step explanation:

i'm probably overcomplicating because i haven't dpne these problems in a while and i don't remember the formula names so sorry if it sounds confusing:

the angle inscribed in the circle has an angle of 64 degrees, so the angle of the minor arc that the inscribed angle creates has an angle of 128 degrees (angle of arc = 2 times angle of inscribed angle'

now using the formula for the tangent lines, x=(major arc-minor arc)/2, the major arc=360-minor arc=360-128=232 so we have (232-128)/2=104/2=52 so x=52 degrees

Answer:

D

Step-by-step explanation:

Draw the central angle from the two tangent points. That angle will be twice the size of 64. So the central angle is 128.

x is the supplement of 128 or 52 degrees. You can show this by proving that the the central angle + x + 90 + 90 = 360

Central angle + x = 180

128 + x = 180

x = 52

3x^2+6x-11

Step-by-step explanation:

g(f(x)) = g(x^2+2x-4) = 3(x^2+2x-4)+1 = 3x^2+6x-11

Lets write the repeatations

a=c.

Hence this data has no mode.

(4c - 3d)(3c + d) =

= 12c² + 4cd - 9cd - 3d² =

= 12c² - 5cd - 3d²

The expression (4c − 3d)(3c + d) is equivalent to 12c² - 5cd - 3d²

(4c − 3d)(3c + d)

Open the bracket

12c² + 4cd - 9cd - 3d²

Collect like terms

12c² - 5cd - 3d²

Hence, the equivalent value of the expression is : 12c² - 5cd - 3d²

Answer:

45

Step-by-step explanation:

AEF is a similar triangle to ABC. that means it has the same angles, and the sides (and all other lines in the triangle) are scaled from the ABC length to the AEF length by the same factor f.

now, what is f ?

we know this from the relation of AC to FA.

FA = 12 mm

AC = 12 + 28 = 40 mm

so, going from AC to FA we multiply AC by f so that

AC × f = FA

40 × f = 12

f = 12/40 = 3/10

all other sides, heights, ... if ABC translate to their smaller counterparts in AEF by that multiplication with f (= 3/10).

the area of a triangle is

baseline × height / 2

aABC = 500

and because of the similarity we don't need to calculate the side and height in absolute numbers. we can use the relative sizes by referring to the original dimensions and the scaling factor f.

baseline small = baseline large × f

height small = height large × f

we know that

baseline large × height large / 2 = 500

baseline large × height large = 1000

aAEF = baseline small × height small / 2 =

= baseline large × f × height large × f / 2 =

= baseline large × height large × f² / 2 =

= 1000 × f² / 2 = 500 × f² = 500 ×(3/10)² =

= 500 × 9/100 = 5 × 9 = 45 mm²
