3. What is the side length of a square with an area of 144x2?
12
12x
+12x
no solution

Hi there!

Assuming you are talking about , we can proceed with the equation of the area of a square, , where is the side length of the square. We can set to be and solve for  :

Square root both sides to isolate :

Now, we can separate the square root into two parts:

And individually solve:

Thus, your answer is the second choice, 12x.

Hope this helps!

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.
