1. Write 2 expressions that is equivalent to double (3x+4y) 2. Factor the following expression: 4xy+5y

3. Use the distributive property to write the following in expanded form:
1. 5(7h+3m) =
2. e(f+g) =

i don't know sorry this is hard to do

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.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12
