Answer:
Final result :
x + 2
—————
x - 1
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 7 • 3 = 21
Step-2 : Find two factors of 21 whose sum equals the coefficient of the middle term, which is -10 .
-21 + -1 = -22
-7 + -3 = -10 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -7 and -3
7x2 - 7x - 3x - 3
Step-4 : Add up the first 2 terms, pulling out like factors :
7x • (x-1)
Add up the last 2 terms, pulling out common factors :
3 • (x-1)
Step-5 : Add up the four terms of step 4 :
(7x-3) • (x-1)
Which is the desired factorization

Answer:
take square root of both sides. √x^2 = x √36= 6
Step-by-step explanation:
x=6
Answer:
It increases
Step-by-step explanation:
The mean of the given data set of 8 values is 4.75 (
)
Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:
, which is equal to 5
Hope this helps
i got this question too as my homework it so hard ill let you know if i find out the answer.
