Answer:

The sequence is used to prove AD = BC is

First prove ABC is congruent to CDA, and then state AD and BC are corresponding sides of the triangles.

Step-by-step explanation:

let us assume that ABCD is a parallelogram.

thus AB is parallel to CD

AC is become transversal.

Take ΔADC and ΔABC.

∠DAC =∠ BCA

( by property of alternate angle )

AC = AC

( common side of both triangle.)

∠ACD= ∠BAC

( by property of alternate angle )

Thus by using ASA congruence property.

ΔADC ≅Δ ABC

Thus

AD = BC

( By corresponding part of the congruent triangle property )

Hope this helped!

Answer:

7) $4 \ log_3(x) - 4 \ log_3(y)$

9) $5log_4(7) - 5log_4(12)$

11) $5log_5 \ (x) - log_5 \ (y)$

Step-by-step explanation:

$log_3 (\frac{x}{y})^{4}$

----------------------------------------------------------------------------------------------------

Use Logarithm of a Quotient which states

$log_b \frac{M}{N} = log_b M-log_bN$

And also use Logarithm of a Power which states

$log_b\ M^{n} = n\log_bM$

----------------------------------------------------------------------------------------------------

So using these two properties,

7. $4 \ log_3(x) - 4 \ log_3(y)$

----------------------------------------------------------------------------------------------------

For #9, use the same logarithm propertied

$log_4(\frac{7}{12})^5 = 5log_4(7) - 5log_4(12)$

----------------------------------------------------------------------------------------------------

#11 is also the same concept

$log_5\ \frac{x^5}{y} = 5log_5 \ (x) - log_5 \ (y)$

It is not - 5 log5(y) since only x is to the power of 5 not y

----------------------------------------------------------------------------------------------------

Hope this is what you were looking for and helps you! Have a nice day/night :)

Answer:

27.74cm^2

Step-by-step explanation:

area of circle: 3 times 3 times pi = 28.26cm^2

area of square: 8 times 7 = 56cm^2

subtract area of circle from square

56-28.26=27.74cm^2

Answer:

4240 inches²

Step-by-step explanation:

In order to find the amount of film needed, we have to find the surface area of this cuboid.

Formula to Find Surface Area of Cuboid: $2(wl+hl+hw)$ , where w = width, l = length, and h = height.

Now, let's solve!

$2(36*25+20*25+20*36)$
$2(900+500+720)$
$2(2120)$
$4240$

Therefore, the answer is 4240 inches².
