Answer:
The quadratic equation has two complex solutions.
Step-by-step explanation:
5x² + 6x + 2 = 0
To know the the correct answer to the question, we shall determine the discriminant of the equation. This can be obtained as follow:
5x² + 6x + 2 = 0
ax² + bx + c = 0
Comparing the above equation, we can obtain:
a = 5
b = 6
c = 2
Discriminant (D) =?
D = b² – 4ac
D = 6² – (4 × 5 × 2)
D = 36 – 40
D = – 4
Since the discriminant of the equation is less than 0, it means that the equation has no real root ( i.e the equation has two complex solution).
Answer:
x=90
Step-by-step explanation:
First, it would help to make it so that the x's are not next to fractions. To do this, you can multiply all terms in the equation by 45. 45 is the closest common factor of 9 and 5, the denominators of the fractions. The answer would be;
20x+9x=2610
Then solve.
29x=2610
x=90
Answer:
Step-by-step explanation:
1/4 and 2/5
4×5=20
Tan(60)/cos(45) = (sin(60)/cos(60))/cos(45)
= ((√3/2)/(1/2))/(√2/2) = (√3)/(√2/2) = (2√3)/(√2)
= ((2√3)(√2))/((√2)(√2)) = (2√6)/2 = √6
If any step doesn't makes sense, hmu!
2(2x+7) or 4x+14
Add 3x-x+2x to get 4x
Add 19-5 to get 14
