The answer to your "Question" would be A.
If you are trying to find the distance between both points, the answer would be (A). you can find this by simply using the Distance formula and inputting (-4, 1) and (5, 4) into the x1, x2, y1, and y2 spots and finding the answer.
Hope this helped!

Question:
Evaluate the expression 5^x - 3^x for x=2
Answer:
5^x - 3^x for x=2 is 16
Step-by-step explanation:
Given
5^x - 3^x
x=2
Required
Evaluate
When fazed with question like this all you need is to substitute the value of x (or any other variable{s} used) in the expression.
Recall that x = 2
So, you have to substitute 2 for x in 5^x - 3^x
This gives
This can be further solved in 2 ways
1. Solve directly
=
= 16
2. Expand using difference of two squares.
Difference of two squares is represented by
By comparison
becomes
For both ways, we'll arrive at the same answer.
Hence, 5^x - 3^x for x=2 is 16
