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

:)

answerthe vertex form

step-by-step explanation:

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
