"The length of a rectangle is 5/2 units greater than its width"
'greater' here means multiplication, 5/2 units greater or 5/2 times more. So we know that the length is

.
Perimeter of a rectangle is:

Plug in our value for the length:
Answer: C
Step-by-step explanation:
In this problem, you will need to know the different properties of the equation. Which part tells you if this graph is negative or positive? and more.
First, we notice an x as the exponent. This tells us that this is an exponential equation. Therefore, we can eliminate B and D.
Next, how do we know if the equation is growth or decay?
The 3 and 1.5 are both positive. This tells us that this is equation is exponential growth.
You can always graph the equation to make sure you are correct.
Answer:
R is reflexive and transitive but not symmetric.
Step-by-step explanation:
R = {(a, b); a ≤ b}
Clearly (a, a) ∈ R as a = a.
R is reflexive.
Now,
(2, 4) ∈ R (as 2 < 4)
But, (4, 2) ∉ R as 4 is greater than 2.
R is not symmetric.
Now, let (a, b), (b, c) ∈ R.
Then,
a ≤ b and b ≤ c
→ a ≤ c
→ (a, c) ∈ R
R is transitive.
Thus, R is reflexive and transitive but not symmetric.
