Step-by-step explanation:
distribute the -2 to (x+1) you end up with -2x-2=8 (multiplication property). Add 2 to both sides to get rid of the -2 of the left (addition property). 8+2=10. -2x=10 divide the -2 to both sides. x=-5 (division property).
Answer: 8.6:8.6
Explanation:
1:n is the form you want.
n is 8.6. change the n value so it is 1:8.6
1 is 1 times bigger than 8.6
8.6 times 1 is 8.6
so you've got 8.6:8.6
your welcome, i hope this helps

Answer:
The answer to your question is 24x³ - 46x²- 28x + 63
Step-by-step explanation:
Data
(6x² - x - 9)(4x - 7)
Process
1.- Multiply 4x by the three terms of the first polynomial
(6x² - x - 9)(4x) = 24x³ - 4x² - 36x
2.- Multiply -7 by the three terms of the first polynomial
(6x² - x - 9)(-7) = -42x² + 7x + 63
3.- Add both result
24x³ - 4x² - 36x -42x² + 7x + 63 = 24x³ - 46x²- 28x + 63
Answer:
54x^2 + 10x
