solve for the equations :
- 3y + 7 + 3(y-1) = 2(2y+6)
- (x-5)(x+4) = (x+7)(x-6)
- 2(x+1)2(x-2)2 = x(x-3)

The table below shows the height of a ball  x  seconds after being kicked.  what values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x)  =  x2  +  x  +  0based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds?   feet

The lengths of two sides of a right triangle are given. find the length of the third side. round to the nearest tenth if necessary. a) y = 12/5x + 39/5 b) y = 5/12x + 5/39 c) y = 12/5x - 39/5 d) y = 5/12x - 5/39

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.
