Answer:
x^2 - 2x + 6
Explanation:
(x^2 + 1) - (2x - 5)
x^2 + 1 - 2x + 5
x^2 - 2x + 6
Answer:
30t if t ≤ 2
25(t-2) + 60 if 2 < t ≤ 6
160 if 6 < t ≤ 10
Step-by-step explanation:
The angles are complementary.
This means they add to 90 degrees.
(2x + 1) + (x + 5) = 90.
3x + 6 = 90. (Combine like terms)
3x = 84. (Subtract 6 from each side)
x = 28. (Divide 3 from each side)
x = 28
D is correct
This is a tough one hope you get it
