4x^2 -5x+2x^2-8x^3+9-3x

Simplified:

− 8 x ^3 + 6 x ^2 − 8 x + 9

It is the same thing in standard form.

Step-by-step explanation:

I hope this helps! Have a nice day!

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.
