Question 7

<h3>Answer: A) 15</h3>

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

Work Shown:

angle B = angle D = 56

angle C = angle F = 64

The missing angle A adds with B and C to get 180

A+B+C = 180

A = 180-B-C

A = 180-56-64

A = 60

Since angles B and D are congruent, and C and F are congruent, this must mean angle A = angle E. I'm using the angle angle (AA) similarity rule.

angle E = angle A

3x+15 = 60

3x = 60-15

3x = 45

x = 45/3

x = 15

Side note: I'm not sure why your teacher marked angle E as the same as angles C and F.  They should have used another angle marker to indicate that angles A and E are the same.

================================================

Question 8

<h3>Answer: B) 17</h3>

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

Work Shown:

Triangle ABC is congruent to triangle EDF. The order is important. We have A first, then B, then C for ABC. Also, we have E first, then D, then F for EDF.

Therefore, we have these three pairings

  • angle A = angle E
  • angle B = angle D
  • angle C = angle F

We'll first need angle C

A+B+C = 180

C = 180-A-B

C = 180-42-108

C = 30

which we'll then solve for x

angle F = angle C

4x-4 = 30

4x = 30+4

4x = 34

x = 34/4

x = 8.5

which doubles to

2x = 2*8.5

2x = 17

Which of the following is an example of a valid use of the multiplication property of equality? A. to isolate s in the equation
marusya05 [52]

Answer:

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.

Step-by-step explanation:

We have a set of an example of equations; we need to study the use of multiplication property of equality.

A. to isolate s in the equation s – 4 = –12, divide both sides of the equation by.In this sentence, to isolate s we do not need multiplication only addition and subtraction.

B. to isolate s in the equation s – 4 = –12, multiply both sides of the equation by. In this sentence, to isolate s we do not need multiplication only addition and subtraction.

C. to isolate s in the equation –4s = –12, divide both sides of the equation by -4. This sentence is correct, and it uses division. However, we are studying multiplication property not division.

D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1. Firstly, it is a good idea to change both negative signs to positive by multiplying by -1 to isolate s.

Finally, we can conclude that a valid use of the multiplication property of equality is D. to isolate s in the equation –4s = –12, multiply both sides of the equation by -1.

A square banner has an area of (4x^2-12x+9) square inches. Write an expression for the perimeter of the banner.
vladimir2022 [97]
The equation can be written as (2x-3)^2
Ans since it is square, then we can take the root of the equation to find on side of the square, which is (2x-3) and by multiplying it by4, we can find the perimeter.
