Hey there!!

Okay so let's start simplifying this :D

-| -2 + 9|  <---- remember that the "vertical bars" are absolute value signs

Absolute value signs will make any values within them into a positive value even if it was negative in the first place

-|  7 |   <---- first simplify what is within the absolute value signs

<u>- 7</u><u />  <----- this is your final answer!!!


I hope this helps you! ^__^

Help plsss thank youuuu
MArishka [77]

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression x^2+8x+15 which we will factorize to see which of the given options is a binomial factor of it.

x^2+8x+15

Finding the factors of 15 such that when added, they give a result of 8.

x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)

Therefore, we can see that (x+5) is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.

PLEASE HELP!!

Ik this is late, but people who are looking for the answer can see this.

Answer:

an =1/3*6^n-1

Step-by-step explanation:

You should plug in 2 for n in each equation, which, the correct one should give you 2. Then, to make sure, you plug in 3 in the equations that gave you 2.

Example:

an = 1/3 * 6 ^n-1

Plug in 2.

an = 1/3 * 6 ^2-1

an = 1/3 * 6 ^1

1/3 * 6 = 2

Step 2.

an = 1/3 * 6 ^3-1

an = 1/3 * 6 ^2

1/3 * 36 = 12

Hope this helps.
