Which algebraic expression is a difference with two terms? A. 5y – 7 B.5(y – 6) C.3y + 1 D.–2y + 5 + 3

Answers

The algebraic expression is a difference between two terms will be 5y - 7. Thus, the correct option is A.

What is Algebra?

Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.

An algebraic expression that is created by removing two terms is known as a difference between two terms. Only one of the suggested expressions corresponds to this description:

⇒ 5y - 7

The difference between the terms 5y and 7, which are being subtracted from one another, is represented by this equation.

Thus, the correct option is A.

If c = the number of cars in a parking lot, which algebraic expression represents the phrase below? the number of cars increased by 9

Answers

The answer is:
c + 9.
This is because c is the number of cars. If you increase, you are adding. So you are adding 9 to the number you have in the parking lot. This makes your answer c + 9.

Answer: c+9

A large flagpole stands outside of an office building. Marquis realizes that when he looks up from the ground 60m away from the flagpole, the top of the flagpole and the top of the building line up. If the flagpole is 35m tall and Marquis is 170m from the building, how tall is the building?

Answers

The height of the office building is 99.2 meters

The given parameters are:

  • d1: The flagpole's distance from the office building = 60 m
  • d2: Marquis' distance from the office building = 170 m
  • h1: Height of the flagpole = 35 m

The above parameters can be represented using the following equivalent ratio

h1 : d1 = h2 : d2

Express as fraction

(h1 )/( d1) = (h2 )/( d2)

So, we have:

(35)/(60)=(h2)/(170)

Multiply both sides by 170

170 * (35)/(60)=h2

99.2=h2

Rewrite as:

h2 =99.2

Hence, the building is 99.2 meters tall

Answer:

99.17m

Step-by-step explanation:

In the diagram, Marquis is at Point A and the flag pole is length DE, the building is of length BC.

Triangles ADE and ABC are therefore similar right triangles.

Applying this,

[TeX]\frac{|DE|}{|AE|}=\frac{|BC|}{|AC|}[/TeX]

[TeX]\frac{35}{60}=\frac{|BC|}{170}[/TeX]

|BC|=170*35÷60

|BC|=99.17m
