Which expression is equivalent to:x+x+(3x +7

Step-by-step explanation:

hello :

x+x+(3x +7) = x+x+3x+7 = 5x+7

5x + 7

Step-by-step explanation:

to solve the  expression requires following simple steps.

x+x+(3x +7)

we are going to open the bracket by just following the BODMAS rule

remeber the rule says

B bracket open

O of

D division

M multiplication

A addition

S subtraction

x+x+(3x +7)

x + x + 3x + 7

2x + 3x + 7

5x + 7

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.
