Answer:
no
Step-by-step explanation:
4x-12+3x=5+7x-17
7x-12=5+7x-17
so no
The acceleration is 10 because 50 divided by 5 is 10.
Answer:
(u+3)(u-3)
Step-by-step explanation:
u²-9 = u²-3²
a²-b²=(a+b)(a-b)
u²-3²=(u+3)(u-3)
A)

b) i think that you should divide the distance by the circumference :

hope this helps
(I'm not completely sure about part b)
good luck
By looking at the formula you can see that the quadratic part is 0 if you fill in x=3 (you know, 3-3 = 0). The outcome of the formula then becomes y= 0+5.
That gives us point (3,5) as the top of the parabola. So there you go, answer A.
