2 (n+1) + n² + 4 (n-3)
= 2n + 2 + n² + 4n - 12 ...expand by using distributive property
= n² + 6n - 10 ...combine like terms
hope it helps

18x + 8x = -3
26x = -3
x = -3/26
Answer:
The correct answer is 2x - y - 1 = 0
Step-by-step explanation:
To find this, use the ordered pair (1, 1) in any of the equations. If it results in a true statement then this can be an equation.
2x - y - 1 = 0
2(1) - (1) - 1 = 0
2 - 1 - 1 = 0
0 = 0 (TRUE STATEMENT)
a triangle needs to have 180 degrees in all.
65 + 65 = 130
180 - 130 = 50
x = 50 degrees
