a^2+b^2=c^2Rearrange so that c = sqrt(a^2+b^2) = 5.83 cm

This is factorisation by common factor, so we need to write 4x+6x² as a product. First we need to find the highest common factor of 4x and 6x² so that we can take it out, which in th...

Expand brackets on LHS4x+12=2x+8Collect "like" terms4x-2x=8-122x=-4Divide both sides by 2 to solve for xx=-4/2=-2Final Answerx=-2

dy/dx = 9x^2 - 12x + 2

To find the velocity from the displacement you must differentiate the function with respect to time.V = (52)t^(2-1) + (21)t^(1-1) + (40)V = 10t +2To find the acceleration you must differentia...
