The answer is C. Good luck
I don't really know if this is correct but I think it is x+y+z=14
For Question Number one
(2+10)²+4=148
Question Number two:
(6+5)×(8-6)=22
If f(x) = 0 then it is a root
x + 3 = 0
x=-3
f(-3) = (-3)^4 + 10(-3)^3 + 23(-3)^2 - 34(-3) - 120 = 0
x - 2 = 0
x=2
f(2) = (2)^4 + 10(2)^3 + 23(2)^2 - 34(2) - 120 = 0
Yes it is because 5 5/8 it’s bigger than 5 and 3/6
