What minus what equals 43
i need

(n + 1)^2  - n^2   = 43   simplify

n^2 + 2n + 1 -  n^2  = 43

2n + 1 = 43     subtract 1 from both sides

2n  = 42       divide both sides by 2

n  = 21

So  n + 1 = 22

Proof

22^2   - 21^2  =

484 - 441  =

or 43-0=43

mark brailiest please it would help alot

:)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
