Answer:
If you dump all of them into one box then you know that one is the mixed
(4x+3) (2x-5)
8x^2-20x+6x-15
8x^2-14x-15
D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
Answer:
$4.80
Step-by-step explanation:
6 oranges for 1.80
sp 6 divided by 1.80 comes out to 0.3 per orange
0.3 times 16 comes out to 4.80
therefor $4.80
The roots of 5x² - 4x + 3 = 0 are non-real
Step-by-step explanation:
In the quadratic equation ax² + bx + c = 0, the discriminant is
b² - 4ac, where a , b , c are constant
- If b² - 4ac ≥ 0, then the roots of the equation are real
- If b² - 4ac < 0, then the roots of the equation are non-real
∵ The quadratic equation is 5x² - 4x + 3 = 0
∵ The general form of the quadratic equation is ax² + bx + c = 0
∴ a = 5
∴ b = -4
∴ c = 3
∵ The discriminant is b² - 4ac
- Substitute the value of a , b and c in the discriminant
∴ b² - 4ac = (-4)² - 4(5)(3)
∴ b² - 4ac = 16 - 60
∴ b² - 4ac = -44
∵ -44 < 0
∴ b² - 4ac < 0
∴ The roots of the equations are non-real
The roots of 5x² - 4x + 3 = 0 are non-real
