The number line is a bit hard to read but from the numbers and looks from it, it looks correct
The correct answer for the question that is being presented above is this one:
Identity refers to equation if left and right equation are the same; Contradiction on the other hand, refers to dissimilar left and right equation.
(1) 8x + 24 = 2(4x + 12) => Identity
(2) 5x + 18 - x = 2(2x + 8) => Contradiction
(3) 7(3x - 2) = 20x - 13 => Contradiction
(4) 3x + 2(x - 10) = 5(x - 4) =>Identity
If it moves 29.9 meters a day, then we need to find the total amount of days:
1000 days + 100 days = 1100 days
Since it moves 29.9m per day, we can write:
29.9m x 1100 which equals 32 890m
So it moved 32 890m
F(2)=3(2)^5 - 7(2)^3 - 11(2)^2 + 2
f(2)=(3×32)-(7×8)-(11×4) + 2
f(2)= 96 - 56 - 44 + 2
f (2)= -2
Remainder: -2
....so no its not a factor.
