13 − 2(4 − 5) = 5 − (7 + 8)

15=-10

Step-by-step explanation:

13−2(4−5)=5−(7+8)

Simplify each term.

13+2=5−(7+8)

Add 13 and 2.

15=5−(7+8)

Simplify each term.

15=5−15

Subtract 15 from 5.

15=−10

Hope this helps! :) Plz mark as brainliest

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.

answer: ouch. thats difficult
