What is the value of n?

enter your answer in the box.

If two chords intersect each other inside a circle, the products of their segments are equal.

7(n+4) = 5(n+8)
7n + 28 = 5n + 40
7n - 5n = 40 - 28
2n = 12
n = 6

For anyone who's wondering from the previous answer is 6. ♡ ～('▽^人)

I just finished the test and got it correct, I hope this helps! :))

Dis the solution here

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?
