Pls help quadratic equations

Mathematics
1 answer:
umka21 [38]3 years ago
3 0

Answer:

n = 5

Step-by-step explanation:

3 x (n+1)² = n² + (n+2)² + 34

3n² + 6n + 3 = n² + n² + 4n + 4 + 34

n² + 2n - 35 = 0

(n - 5) (n + 7) = 0

n is a positive number

n = 5

check: 5, 6, 7

6 x 6 x3 = 108

(5 x 5) + (7 x 7) + 34 = 25 + 49 + 34 = 108

For which function is the ordered pair (2, 12) not a solution?
Delicious77 [7]
The x-coordinate is 2 and y-coordinate is 12.

Substitute 2 into x then check if y is equal to 12.

D is the answer since y = (2) - 10 = -8, not 12.
