trapezoid
step-by-step explanation:
first i plotted all my points on a grid graph
i made sure all of them were in the correct quadrant
then i saw it was a trapezoid or a quadrilateral
a. 12.5 kg
f = ma
so
m = f/a = (2500 n)/(200 m/s²) = 12.5 kg
1 n = 1 kg·m/s²
there is no graph so i cant sorry
given the equation is 8+9z=-6, the first step would be to subtract the 8 from both sides:
8+9z-8=-6-8
since 8 minus 8 = 0, this would cancel out the 8. and since -6 minus 8 equals -14, the equation would look like this
9z = -14
