Hey there I see you need help well I am here to do just that so for this question you do 5^23 - 5^21 = 5^21(5^2 - 1) = 5^21(25 -1)= 5^21(24)
so 5^21(24) is the answer
i hope this helps

For this question you can say:(we factor it out)
5^23 - 5^21 = 5^21(5^2 - 1) = 5^21(25 -1)= 5^21(24)
so 5^21(24) is the answer :))))
i hope this is helpful
have a nice day

State if the triangles in each pair are similar.If so, state how you know they are similar and complete the similarity statement.
A) similar; SAS similarity; ΔBAC
B) not similar
C) similar; SSS similarity; ΔABC
D) similar; SAS similarity; ΔABC

Answers

Answer: The correct option is

(C) similar; SSS similarity; ΔABC.

Step-by-step explanation: We are given to check whether the pair of triangles in the figure are similar to each other or not.

If so, we are to complete the similarity statement.

From the figure, we note that

the lengths of the sides of triangle STU are

ST = 72, TU = 80 and SU = 56.

And, the lengths of the sides of triangle ABC are

AB = 27, BC = 30 and AC = 21.

So, we get

$(ST)/(AB)=(72)/(27)=(8)/(3),\n\n\n(TU)/(BC)=(80)/(30)=(8)/(3),\n\n\n(SU)/(AC)=(56)/(21)=(8)/(3).$

That is,

$(ST)/(AB)=(TU)/(BC)=(SU)/(AC)=(8)/(3).$

Therefore, the corresponding sides of the two triangles are proportional.

Hence, triangle ABC and STU are similar by SSS similarity.

Option (C) is CORRECT.

Answer:

Option C) similar; SSS similarity; ΔABC

Step-by-step explanation:

we know that

The SSS similarity state : If the corresponding sides of two triangles are proportional, then the two triangles are similar

In this problem

80/30=56/21=72/27

2.67=2.67=2.67 -----> is true

therefore

The triangles STU and ABC are similar by SSS similarity

Brinn's rectangular kitchen has an area of 81 square feet. The kitchen is 9 times as many square feet as Brinn's pantry. If the rectangular pantry is 3 feet wide, what is the length of the pantry?

Answers

the length of the pantry is 3 feet. this is because if the pantry is 9 times smaller than the kitchen, the area of the pantry must be 9 feet. Therefore, if the width of the pantry is 3 feet, the length of the pantry must be 3 feet.

Suppose that on a coordinate plane a hexagon is reflected across the x-axis. Compare the area of the original hexagon to the area of the transformed figure. Justify your answer. A) The areas may or may not be the same because the scale is not given. B) The areas are equal. A reflection is a rigid transformation, which does not change the size of the original hexagon. Therefore, the area is preserved. C) The area of the original hexagon is greater than the transformed figure. A reflection decreases the size of the original polygon. Therefore, the area is not preserved. D) The area of the transformed hexagon is greater than the original figure. A reflection increases the size of the original polygon. Therefore, the area is not preserved.
