Fill in the value which would complete the square:
X^2 + 10x +

25

Step-by-step explanation:

(x+5)(x+5)=x(x+5)5(x+5)

=x^2+5x+5x+25

=x^2+10x+25

i hope it is clear

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

for any of you who need the translation here it is
