Answer 1
Answer:

Question:

The perimeter of an equilateral triangle is 9n - 12. Write an expression to represent the length of each side.

Solution:

  • The perimeter of an equilateral triangle is 9n - 12.
  • We know, perimeter of a triangle is the sum of the three sides of the triangle.
  • Also, in an equilateral triangle, all the sides are equal.
  • Therefore, the length of each side of the triangle

= (9n-12)/(3) \n = (3(3n - 4))/(3) \n = 3n - 4

Answer:

The length of each side of the triangle is 3n-4.

Hope it helps!!
Answer 2
Answer:

Answer:

9n - 12 \rightarrow (1)/(3) (9n - 12) \n = (3)/(3) (3n - 4) \n l = 3n - 4

Jerry bought a bottle of perfume for a gift for his wife.The perfume cost $92 before tax.

If the total price including tax was $98.90, find the tax rate.

Answers

First, you need to find how much money the tax was (98.90-92=6.9) Then, divide the tax by the price without the tax to find the tax rate (6.9/92=.075) then multiply the answer by 100 (.075*100=7.5)The tax rate is 7.5%

Review the graph.What is the magnitude of the vector shown?

The required magnitude of the vector is √13. Option D is correct.

A graph is given, that shows the vector, the magnitude of the vector is to be determined.

What is vertex form?

Vector form is defined as representing any point in space that has both magnitude and direction.  A point k in space is represented as a vector OKi + OKj, which denotes the vector line, OK joining the line from the origin O to the point k. The vector form is used to define a line or a plane in a 3D space.

From the figure,
given vector can be expressed as,
\bar v = 3\bar i+2\bar j
now the magnitude of vactor,
|\bar v| = √(3^2+2^2)\n|\bar v| = √(9+4)\ \n|\bar v| = √(13)\

Thus, the required magnitude of the vector is √13. Option D is correct.

A basketball player has already scored 56 points in a game. The team record for points in a game is 72. Which equation would allow you to find out how many more points the player needs to tie the record?a. 72 + x = 56
b. 56 − 72 = x
c. 56 + x = 72
d. 56 + 72 = x

Answers

C. 56 + x =72 because the team player already scored 56 points you would need to add an unknown amount of points in this case x to find out how many points you need in order to reach 72 points and if you are curious how many points you need in order to get to 72 you need 16 points.

Answer:

C. 56 + x =72
