Answer:
1.) n = - 5/2
2.) No solution
3.) n = - 2/5
Step-by-step explanation:
1.) n(- 2) = - 1 - (- 2) + 4
- 2n = - 1 + 2 + 4
- 2n = 5
n = - 5/2
2.) n(0) = - 1 - (0) + 4
0 = - 1 - 0 + 4
0 = 3
No solution
3.) n(5) = - 1 - (5) + 4
5n = - 1 - 5 + 4
5n = - 2
n = - 2/5
2 3/20 ,2 9/20, 2 1/2,2 11/20,2 4/5
Answer:
x = 28
Step-by-step explanation:
angle 1 and angle 2 are complementary (their sum is 90°)
x + 5 + 2x + 1 = 90 add like terms
3x + 6 = 90 subtract 6 from both sides
3x = 84 divide both sides by 3
x = 28
