Answer:
Rate of change of the area of the square is 42 units at t = 2.
Step-by-step explanation:
We note that the area of the square is given by: 
but we aim to find 
. But we can use the chain rule to pull out that dA/dt. Doing so gives us:
Now, 
(by the power rule and 
But since we have "x" and not "t", we want to find what x is when t = 2. Substituting t = 2 gives us x(2) = 3(2) + 1 = 7.
So, finally, we see that:
C would equal -3 because you are going up 9 units
Since angles 3 and 4 form a linear pair, the sum of the measures of their angles must add up to 180.
We can define angle 3 as x, and angle 4 as (180-x).
x = 3 ( 180 - x ) + 4.
Solving for x, we get x=138. This is angle 3. Angle 4 is 180-138, so angle 4 is 42.
22 = 2 · 11
2 is even
11 is odd
LCM(2; 11) = 22
but we have other answer:
22 = 1 · 22
22 is even
1 is odd
LCM(1; 22) = 22
Answer: 2 and 11 or 22 and 1.
