Which of the following represents the factorization of the binomial below ? x^2 - 144
Dima020 [189]

It factors to (x+12)(x-12)

This is the same as (x-12)(x+12) as we can multiply two expressions in any order we want. This is like saying 7*5 is the same as 5*7

I used the difference of squares rule to factor x^2 - 144. It might help to write x^2 - 144 as x^2 - 12^2, then compare it to a^2 - b^2 = (a-b)(a+b)

A survey of 500 high school students was taken to determine their favorite chocolate candy. Of the 500 students surveyed, 42 lik
Step2247 [10]

Answer:

Step-by-step explanation:

Universal set

U = 500

The number that likes snickers

n(S) = 42

The number that like Twix.

n(T) = 110

The number that like Reeses

n(R) = 125

n(S n T) = 33

n(T n R) = 62

n(S n R) = 26

n( S n R n T) = 22

Then,

n(S n T) only = n(S n T) - n(S n R n T)

n(S n T) only =33 - 22 = 11

n(T n R) only = n(T n R) - n(S n R n T)

n(T n R) only =62 - 22 = 40

n(S n R) only = n(S n R) - n(S n R n T)

n(S n R) only =26 - 22 = 4.

Also,

n(S) only = n(S) - n(S n R) - n(S n T) only

n(S) only = 42 - 26 - 11 = 5

n(T) only = n(T) - n(T n R) - n(T n S) only

n(T) only = 110 - 62 - 11 = 37

n(R) only = n(R) - n(S n R) - n(R n T) only

n(R) only = 124 - 26 - 40 = 58

Then, to know if some student don't like any of the of chocolate,

Let know the number of students that like the chocolate candy

n(S) + n(T)only + n(T n R)only + n(R) only

42 + 37 + 40 + 58 = 177 students.

Therefore, the total students that like chocolate candy is 177, so those  that does not like any of them are

n(S U R U T)' = U – n(S U R U T)

n(S U R U T) = 500 - 177 = 323.

So, the question is how many student likes at most 2 kinds of these chocolates, this means that they can like exactly 2 or less or even none.

So, this category are

n(2 most) = n(S n T)only + n(R n T)only + n(S n R)only + n(s)only + n(T)only + n(R)only + n(S U R U T)'

n(2 most) = 11 + 40 + 4 + 5 + 37 + 58 + 323

n(2 most) = 478

The correct answer is E.

ad-work [718]

Answer:

Ashanti and Landry will for 7 hours to wash 56 cars

Step-by-step explanation:

* Lets explain how to solve the problem

- When to people work together to finish a job, we multiply the rate of

  each by the time and add them,then equate the answer by the job

- <u><em>Lets do that with Ashanti and Landry</em></u>

- If Ashanti can wash 3 cars per hour

∴ The rate of Ashanti is 3 car per hour

- If Landry can wash 5 cars per hour

∴ The rate of Landry is 5 car per hour

- When they work together they will wash 56 cars

∵ They work together then they will work same amount of time

- <u><em>Let the amount of time they will work is t</em></u>

∵ Ashanti and Landry will work together for t hours to wash 56 cars

∴ 3t + 5t = 56

∴ 8t = 56

- Divide both sides by 8

∴ t = 7

∵ t represents the time they will work together

* Ashanti and Landry will for 7 hours to wash 56 cars
