P(n) = 2n^2 + 2n; find p(-6)
P(-6) = 2(-6)^2 + 2(-6)
P(-6) = 2(36) - 12
P(-6) = 72 - 12
P(-6) = 60

Answer:
P(-6) = 60

Solve each given equation and show your work.
Eduardwww [97]

Answer:

(a) x = 3

(b) y = 6

(c) false/not true

(d) x = 5

Step-by-step explanation:

(A) 2 + x = 5 You would subtract the 2 from both sides which gives you x = 3

(B) 8y = 48 You would divide 8 from both sides which is 6 so y = 6

(C) 23 = 26 That is not true because 23 does not equal 26

(D) -7x - 3x + 2 = -8x - 8 First simplify the equation; -10x + 2 = -8x - 8. Next, you want to subtract 2 from both sides which gives us -10x = -8x - 10. Now you want to add 8x to both sides which is -2x = -10. And now you just divide -2 on both sides which gives us the answer 5. So, x = 5. I hope this helps. Let me know if one of the answers are incorrect.

If i had the equation -3y=-2x+8 would i divide the 8 by -3 too?
UNO [17]
Not only you're gonna divide 8 by -3 for some reason, but you also divide all terms by -3. For instance,
(-3y = -2x + 8) / -3
(-3/-3)y = (-2/-3)x + 8/-3
y = (2/3)x - 8/3

Hope this helps.
