Answer:
Step-by-step explanation:
2x²-2x=3
2x²-2x -3 = 0
note :
the discriminat of each quadratic equation : ax²+bx+c=0 ....(a ≠ 0) is :
Δ = b² -4ac
1 ) Δ > 0 the equation has two reals solutions : x = (-b±√Δ)/2a
2 ) Δ = 0 : one solution : x = -b/2a
3 ) Δ < 0 : no reals solutions
***** in this exercice : a = 2 b = -2 c = -3
Δ = (-2)² -4(2)(-3) =28
x = (2±√28)/6
The answer is [c.]

Answer:
because it may not be suitable for all the time
When dividing 1/8 by 2
we have to first take the reciprocal of 2
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is

we need to find the reciprocal of

which is

then

when 'of' function is used it means to multiply the 2 fractions
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators
is

answer is
Hello there! Thank you for asking your question here at Brainly! I will be assisting you today with answering this problem, and will teach you how to handle it on your own in the future.
First, let's take a look at our problem.
"The speed of a ship is given by D3, where D is the distance the ship travels in 3 hours. If the ship travels 48 miles in 3 hours, what is the speed of the ship?"
To solve for this, we need to understand the formula for speed.
The formula for speed is:
Speed = 
Now that we have our formula, let's
define our variables.
So, we have our distance, 48 miles, and our time, 3 hours.
Let's
plug in these numbers to the formula.
Speed =
Simplify the fraction to get the speed.

= 16.
Your final equation is:
Speed = 16.
Our final answer is
16 mph.I hope this helps!
