If n is an odd number greater than or equal to 3, can n + 1 ever be prime? What if n equals 1?

No, because when adding 1 to any odd number it will become even, and all even numbers besides 2 are not prime. This means that if n was 1 the resulting number would be prime, since 2 is prime.

Which of the following represents the factorization of trinomal below
My name is Ann [436]
A is the correct answer.......

Here is the work shown:

x^2-x-20

A is the correct answer because when using the distributive property it is the only example that results in x^2-x-20.

(x+4)(x-5)

x*x=x^2, x*-5=-5x, 4*x=4x, 4*-5=-20. Now combine all alike terms for your final answer. x^2-x-20..

What is the answer for this one ??
Arisa [49]

Answer: D

Step-by-step explanation:

A. 3 + -7 < -4

    -4 < -4

        X

    this one isn’t a solution

B. 3 + -7 ≤ -4

   -4 ≤ -4

   this works, let’s try the other equation

   3(3) + 2(-7) < -5

    9 + -14 < -5

     -5 < -5

       X

     this one doesn’t work either, let’s go on to the next one

C. the first equation is the same as the first one in A, and that didn’t work, so we know that the whole thing doesn’t work and we don’t have to do any math

D. we know the first equation works because we did it in B

    let’s go on to the second equation

    3(3) + 2(-7) ≤ -5

     9 -14 ≤ -5

     -5 ≤ -5

      this works, so that means that both equations work and the whole thing works :)

yarga [219]

Answer:

Option B is the correct choice.

Step-by-step explanation:

As Jason used his car as collateral to borrow money from his bank and now he is unable to pay the loan. The car was a sort of guarantee against the loan. The loan must be of lesser amount than the car's value. Hence, the bank will sell of the car and recover its money. So, option B - The bank will seize the car and likely sell it to pay off Jason’s loan. -is right.
