I'm glad to hear that, but where is the math problem?
4x^2 + 16x-2= 5x
Minus 16x over
4x2-2= -11x
Add 11x over
4x^2 +11x -2
Use quadratic formula x= 2.9
I’m not sure here. I tried my best. Hope it helps!
Without the table I will guess 5 is common to all 3 they are proportional
That equals 27 hope this helps
Answer
Speed depends on the amount of force you put into it... it the force is the same on the each surface then it will depend on the roughness of the surface as in friction
