Choose the example below that can be the first step to factoring by grouping for the following polynomial.

D

Step-by-step explanation:

The problem given is  

For factoring by grouping, we can "group" first & third terms and then "group" 2nd and 4th term.

Note: Then, we find the "common factor" in the first grouping and then find the "common factor" in the next grouping. Then, we simplify.

Since we don't have to factor this, as the problem doesn't demand it, we don't do it.

From our grouping, we see that answer choice D is same. So answer is D.

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.

median is the value separating the higher half of a data sample, a population or probablity distribution from the lower half.

step-by-step explanation:

say you have 3,8,7,3,1,9,8 order them from lowest to highest

if orderd it would be 1,3,3,7,8,8,9 now you take away from the lowest and the highest until you end up in the middle.

so you would remove the 1 and 9 leaving you with 5 digits remaining

when you've reached the middle that would be your answer so in this case the answer is 7

if there were two numbers left say 7 and 5 you'd and them together so 12 then divide by 2 witch would equal 6 so the answer would be 6

good luck on that project hoped i you at all
