Answer:

B. 0 m

Step-by-step explanation:

We are given the movement of an object and are required to find the total displacement.

Now, as we know that 'displacement' refers to the length of the shortest path between two points.

i.e. We are required to find the shortest path the object covers.

Now, we can see from the figure below that the given movement,

40 m north → 40 m west → 40 m south → 40 m east,

will bring the object back to the original position ' O '.

Hence, the total displacement will be 0 m.

Pls only answer if yk it ill give correct one BRAINLIEST!!
Dmitry [639]

Answer:

X=10, x=4

Step-by-step explanation:

first, divide 14 by 2, and square it; giving you

x^2-14x+(7)^2=-40

Because 7^2 is 49, you have to add 49 to the other side; giving you

x^2-14x+(7)^2=9

Then factor the left side; giving you (x-7)^2=9

Take the square root of both sides, giving you

(x-7)^2= plus or minus 3

Then solve to get two solutions, 10 and 4
