carlas rectangular picture frame is 10 inches wide and 12inches long, which picture frame is similar but not congruent to carlas picture frame

(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:

Answer: k - 16

Step-by-step explanation:

If she looses, it becomes less or smaller. Subtraction produces that result. K is a fairly large number. 16 is much smaller. So she has K - 16 left.

K - 16

We have that

The  interval equivalent to each range is given below

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

[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:

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

Answer D but read below.

Step-by-step explanation:

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.

However I think you are expected to answer F which is answer D.

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:

rational integer and whole

Answer:

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.

One circle is 360°, that means, 180° is half of the circle.

Then, the required rotation may be performed according to this property. For more details see the attached picture.

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
