Answer:
A
Step-by-step explanation:
Solve the equation using the quadratic formula ⇨ x² + 11x + 9 = 0
All equations of the form can be solved using the quadratic formula: . The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
This equation is in standard form: ax² + bx + c = 0. Substitute 1 for a, 11 for b and 9 for c in the quadratic formula .
Square 11.
Multiply -4 times 9.
Add 121 to -36.
Now solve the equation when ± is plus. Add -11 to √85.
Now solve the equation when ± is minus. Subtract √85 from -11.
The equation is now solved. The solution set is :-
B is not a geometric sequence
68 degrees as well, because the angles are corresponding.
Answer:
The answer is (60,90)
Step-by-step explanation: Because if u think white is added by 12 like 24+12 is 36 same as for Pink 18+18 is 36 adding up
