Answer: -26
Step-by-step explanation:
2(n - 4)= 3(n + 6)
2n -8 = 3n + 18
+8 +8
2n = 3n + 26
-3 -3
-1n = 26
n= -26
Step-by-step explanation:
2(5) - 4(1) +3 =9
10 - 4 +3 = 9
Three consecutive numbers can be written as x, x+1, and x+2, but they also can be written x, x-1, and x-2 where x is the biggest number.
sum means adding... so

combine like terms and solve for x!
The derivate is. f'(x)=2x+1 .then f'(-1)=-2+1=-1
