Answer:
-1.4 and 3.4
Step-by-step explanation:
The solutions of a quadratic are the x values of the x-intercepts where the function crosses the x-axis.
Type in your equation to graph. Then zoom in on the x-axis and find where the function crosses.
See attached picture.
<span>K = 3D. K - 4 = 5(D - 4). K - 4 = 5D - 20. K = 5D - 16. 3D = 5D - 16. 16 = 2D. D = 8. K = 3 x 8. K = 24.</span>
All you have to do is divide each one by its other number. For example, 5.60 for 8 is the same as one for 0.70. We accomplish this by dividing the 5.60 by 8.
So...
0.70
0.80
0.90
0.75
The first choice is the lowest.
Answer:

Step-by-step explanation:
As we can see the given expression as three complex parts and all are being multiplied.
Lets simplify each part separately and then multiply all of them in the end
Part1
Cancelling 8 in numerator with 8 in denominator



Part2

simpliying



Part3
Third part is
, and it does not need to be further simplified
Now multiplying all the three parts





So our final answer is
