When the X term is one, and doesn't have a leading coefficient, then you can factor it using the box and diamond method. look up videos on Khan Academy of the box and diamond method for solving trinomials. For number 9, you have a difference of squares. That means you can factor to just 2 terms. (x+4)(x-4) this works because 16 has an easy square root, and the sign in between is a negative(difference)

Is 17.8 = 18.8 reasonable explain.
yaroslaw [1]

Answer:

No.

Step-by-step explanation:

For there to be a equal sign, it will mean that both sides will have to have the same exact amount. If it is expressions on both sides, then the expressions must, when combined, equal to each other.

In this case, there is not given operation that will allow for both numbers to equal each other, and 17.8 is 10 less than 18.8, therefore it is not reasonable.

17.8 ≠ 18.8

A bag holds 12 red marbles, 11 green marbles, 17 blue marbles and 5 yellow marbles. What is the probability that you will NOT ch
AysviL [449]

Hello! The answer to your question woulds be as followed:

We have to find how many marbles are in total first

12 + 11 + 17 + 5

= 45

Since we want to find the probability that you will NOT choose a blue marble, we have to find how many aren't blue

12 + 11 + 5

= 28

We have a probability out of 48 now, therefore

<u><em>28/48 would be our fraction, </em></u>

<u><em>To simplify:</em></u>

<u><em>7/12 or about 58.33%</em></u>
