You haven't shared "the given value of x," or, if you have, you haven't drawn attention to it.
Just suppose we were to choose x = 4 as a possible solution and then try to find a value of the parameter k that would make x = 4 an actual solution.
2(4) + 4k - 9 = (4)(4) - (4) + 1
Then 8 + 4k - 9 = 16 - 4 + 1, or 4k - 1 = 13. Then 4k = 14, and k = 14/4, or (after reduction) k = 7/2
If the parameter k equals 7/2, then x = 4 is a solution to the given equation.
To check this out further, start with the proposed solution x = 5 and find k.
Answer is 5.85 see picture
Answer:
26.2 inches cubed
Step-by-step explanation:
The volume of a cone is denoted by:
, where r is the radius and h is the height.
Here, we are given that the diameter is 5. Remember that the radius is simply 1/2 the diameter, so the radius is r = 5/2 = 2.5. We are also given that the height is h = 4. Plug these into the equation:

≈ 26.2
Thus, the volume is about 26.2 inches cubed.
Hope this helps!
The length of the toy tractor is 3.125ft
Data Given;
To solve this question, we need to find the length of the tractor using ratios.
<h3>What is Ratio</h3>
This is the proportion of a substance to the entire value of that substance.
If the length of the tractor is 25 ft, then the length of the toy tractor can be found when we divide 25 by 8.

The length of the toy tractor is 3.125ft.
