Answer:

x =5.5

Step-by-step explanation:

The directions say to use x for the number.

"take 10 away from"

x - 10

"then square the result"

(x - 10)^2

"I get the same answer" means the two expressions will be equal to each other.

"if I square my number"

x^2

"then subtract 10 from the result"

x^2 - 10

SET EQUAL TO EACH OTHER.

(x - 10)^2 = x^2 -10

Multiply on the left side.

x^2-20x+100 =x^2-10

subtract x^2 from both sides.

-20x + 100 = -10

subtract 100.

-20x = -110

divide by -20

x = 11/2 or 5.5

CHECK:

(5.5-10)^2=20.25

5.5^2 - 10=20.25

The answers to the following question is

1) KL = 10

2) TE= 15 cm

3) angle PUT= 13

4) angle SQP = 21

<h3>What is similarity in triangle?</h3>

Two triangles are similar if they have the same ratio of corresponding sides and equal pair of corresponding angles. If two or more figures have the same shape, but their sizes are different, then such objects are called similar figures.

1) Using similarity property in given triangle

SR/ KI= SJ / JK

AS, JK= 2 SJ

SR/ KI= SJ / 2 SJ

5/ KI =  1/2

KL= 10

2) As, the diagonal of parallelogram bisect equally each other then

VE = TE

AS, VE = 15

So, TE= 15 cm

3) As, PU is the bisector of angle SUT

angle PUT= 1/2 (angle SUT)

PUT = 1/2 (26)

angle PUT= 13

4) As PQ is the bisector SQR

angle PQR= angle SQP = 21

6^4 • 3^4 and 18^8, Are the expressions equivalent? I’m only talking about C in the photo.
Afina-wow [57]

Hey there!

6^4 * 3^4 = ?

6^4

= 6 * 6 * 6 * 6

= 36 * 36

= [1,296]

3^4

= 3 * 3 * 3 * 3

= 9 * 9

= [81]

1,296 * 81

= [104,976]

6^4 * 3^4 = [104,976]

Now let’s see if 18^8 is equivalent to 18^8

18^8

= 18 * 18 * 18 * 18 * 18 * 18 * 18 * 18

= 324 * 324 * 324 * 324

= 104,976 * 104,976

= [11,019,960,576]

Therefore, 11,019,960,576 ≠ 104,976 because It is way too big to be equations answer

Answer: [NO], they aren’t equivalent because 18^8 is too big to equal to 6^4 * 3^4

Good luck on your assignment and enjoy your day!
