Answer:
A
Step-by-step explanation:
We take a look at this expression:
and notice that both terms are square numbers.
and
.
There is a specific formula that I highly recommend you memorize involving differences of squares. It states that given the difference of squares
, it can always be factored into
.
Here, we can apply that. In this case, a = 7x and b = 3. So:

Thus, the answer is A.

Answer:
The explanation is given below with the diagram.
Step-by-step explanation:
Given:
Δ ABC is an Isosceles triangle with base AB.
D is the midpoint of AB
∴ AD = BD
To Prove:

Proof:
Isosceles triangle property:
If Δ ABC is an Isosceles triangle with base AB, then the two sides are congruent and the base angles are congruent.



Like this variation of the problem! :)
We calculate the future value of the 6 annual deposits of $1500 at 8%:
F=1500(1.08^6-1)/(0.08)=11003.89
Since the last payment is due on the day of withdrawal, he would have paid $1500 to get back $11003.89, i.e. with an excess of 1003.89.
Therefore his last payment is 1500-1003.89=$496.11
