Answer:
8. 11v
9. -19x
10. 6p
11. 16n
12. -4n - 5
13. 15r
14. 9n + 1
Step-by-step explanation:
8. -v + 12v = 11v
9. -8x - 11x = -19x
10. 4p + 2p = 6p
11. 5n + 11n = 16n
12. n + 4 - 9 - 5n = n - 5n + 4 - 9 = -4n - 5
13. 12r + 5 + 3r - 5 = 12r + 3r + 5 - 5 = 15r
14. -5 + 9n + 6 = 9n + 1
Answer: 153.86
Step-by-step explanation:
Area of circle = r^2*3.14
r=7
7^2*3.14= 153.86
The correct simplification would be x^14/y^18
Answer: 36x-30
Step-by-step explanation:
6 times 6x is 36x and 6 times -5 is -30

Suggesting that you want this in standard form, in terms of quadratic equations, you would technically follow a process similar if not almost exactly like the 2 - step equation method with the exception of separating the (x)s and the equations to find x and then plug it in and what-not.
With that being said you would subtract 5 in (x+5) from said 5 in the second equation and -10 in the first equation in order to get 2x^2+7x-15, you would continue to do the same for the x by subtracting it from both ends making the 7x a 6x because there is a 1 at the beginning of each x if there is no number that is shown already. Which finally gives you the equation (y= 2x^2+6x-15)
