1. An equilateral triangle has a perimeter of 6x + 3 centimeters. Write an expression that correctly represents the length of one side of the triangle.

2. Jayden walked a total of 12x+5r-8 miles on Monday and Tuesday. If he walked 7x-10r miles on Monday, how many miles did he walk on Tuesday?

3. A stop sign is in the shape of an octagon. Find the perimeter if each side is 2a + 1 units.

4. Write the expression for the perimeter of a rectangle with a length that is 4 centimeters longer than three times it’s width

HELP PLEASE!

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.
