Can someone help me ?

B

Step-by-step explanation:

If you factor B you get:

y =

The points where the graph crosses the y axis are the x-intercept, meaning that y = 0 there.

Therefore:

x^2 + 3 can't be equal to zero because the square root of a negative number does not exist. Therefore, the only zero is x = 7 so it only crosses the x-axis in one place.

You can check the others the same way by factoring, but this is the only one with a single solution.

10.416 m/s

step-by-step explantion:

distance=100m

time= 9.6s

average speed=100/9.6

=10.416 m/s

95.03 is the answer. hope this !
