To find the roots, we need to factorize the quadratic expression
x² + 6x - 55 = 0
x² + 11x - 5x - 55 = 0
x(x + 11) - 5x - 55 = 0
x(x + 11) -5 (x + 11) = 0
(x - 5)(x + 11) = 0
Then solve the value of x
x - 5 = 0
x = 5
or
x + 11 = 0
x = -11
The roots are -11 and 5
Sum of the roots
sum = -11 + 5
sum = -6
The answer is option b
Answer:
In any instance.
Step-by-step explanation:
A triangle has three sides, and the angle measures for all three angles will add up to a total of 180°.
∠A + ∠B + ∠C = 180°
<u><em>Example:</em></u>
Find ∠C if ∠A = 60° and ∠B = 50°.
60° + 50° +∠C = 180°
∠C = 70°
12:30
A to B
30 + 12 is 42
so... the final answer would be 12:30.
Answer:
the answer is 60045
Step-by-step explanation:
the answer is 60000 because 6×10=60×100=60000+45=60045
