Answer:
(3 ± √23 * i) /4
Step-by-step explanation:
To solve this, we can apply the Quadratic Equation.
In an equation of form ax²+bx+c = 0, we can solve for x by applying the Quadratic Equation, or x = (-b ± √(b²-4ac))/(2a)
Matching up values, a is what's multiplied by x², b is what's multiplied by x, and c is the constant, so a = 2, b = -3, and c = 4
Plugging these values into our equation, we get
x = (-b ± √(b²-4ac))/(2a)
x = (-(-3) ± √(3²-4(2)(4)))/(2(2))
= (3 ± √(9-32))/4
= (3 ± √(-23))/4
= (3 ± √23 * i) /4
To convert ANY percent to a decimal we need to divide the percent by 100. Lets do it:-
60%
60 ÷ 100 = 0.60
60% written as a decimal is 0.60.
CHECK OUR WORK:-
0.60 × 100 = 60
We are RIGHT!!!
So, 60% written as a decimal is 0.60 (0.6).
Hope I helped ya!! xD
Answer: -9
Step-by-step explanation:
(6+3)÷(4-5)
Since 6+3 is 9 and 4-5 = -1
You do 9 divided by -1. It equals -9.
It is -9 since a positive divided by a negative number.
Answer:
£55.25
Step-by-step explanation:
Cost after reduction
=Cost before sale - Reduction in cost
= 85 - 35% of 85
= 85 - 0.35*85
= 85 - 29.75
= £55.25
