Find the missing factor. 7s2 + 25s + 12 = (s + 3)( ).

Step-by-step explanation:

First part of the second factor.

Start by noticing that you are not going to get 7s^2 with the factor you have. So the first thing to do is to write the second factor as

(s + 3)  (7s

Sign

The next problem is to figure out what the sign following the 7s is. The 12 holds the answer to that.

12 is positive. So what ever follows must also be positive. Otherwise you will get a negative for the 12.  So now you have

(s + 3)(7s +

What comes after the Plus Sign?

Last step. you need a number that when multiplied by 3 will give you 12. That has to be 4

(s + 3)(7s + 4) This is your answer.

blue marble is 15 times out of 50 = 15/50 reduces to 3/10

landing on tails is 24 out of 50 = 24/50 reduces to 12/25

to find the probability of both multiply together:

3/10 x 12/25 = 3 x 12 / 10 x 25 = 36/250

if you multiplied the numerator and denominator by 10 you get 360/2500.

the answer is 360/2500

points are handed out whenever you post answers.

brainliest answers are handed out by the person asking the question, so whether your answer is picked depends entirely on whether the asker bothers to pick

if you're asking about your rank, it depends on having a certain number of points and a certain number of brainliest answers. for example, at the time of this writing, i have 44338 points out of 15000 needed for the next (nearly triple the requirement! ) but i only have 24 out of 50 required brainliest answers. this number decays, meaning after a certain amount of time (i think about a month), the total number of brainliest answers you've earned doesn't count toward this total. (i've been stuck at the same rank for a long

the lesson to learn here is that you shouldn't worry about points or rank. chances are, no matter how good an answer you may provide, your efforts will go mostly unnoticed unless you focus on the newest/most active questions that get posted.
