3x - 18 = 42
3x = 42 + 18
3x = 60
x = 60/3
x = 20
Answer:
3.4
Step-by-step explanation:
will 3.4 is is rounded of 54256 in decamal
The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
Answer:
So sorry , but the pic isn't very seen well
The quotient will be less that 34 because 78 divided by 34 is 2
