How do I find out the exact solutions and approximate solutions?

Approximate solutions are x = 2.828 and x = - 2.828
The attachment shows a portion of the graph with this equation. The "zeros" are the solutions.
Step-by-step explanation: To get values for x, we need to isolate x
2x² -6 = 10 Add 6 to both sides and rewrite the equation as
2x² = 16 divide both sides by 2
x² = 8 Factor 8 as 4(2) so you can "pull out" a square.
To solve for x, take the square roots of both sides.
Remember that square roots are positive and negative values.
[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{4(2)}[/tex]
x = ± 2√2
x = 2√2 and x = -2√2
We can use a calculator to get approximate values of x.
[tex]2\sqrt{2}[/tex] = ±2.828427125
Round that to x = 2.828 or 2.83 AND x = - 2.828 for approximate values.

The mountain trail at Tanner Park is 8 miles long traveling to the top of the mountain and back. Grayson is making his way back down after hiking 4.6 miles. He needs to hike for another 2 hours to make it to the bottom. How many miles will he hike per hour? 7th-grade question
Answer:
Speed of hike = 1.7 miles per hour
Step-by-step explanation:
Given:
Total distance = 8 miles
Distance already traveled = 4.6 miles
Total time remain to travel = 2 hour
Find:
Speed of hike
Computation:
Distance remain = Total distance - Distance already traveled
Distance remain = 8 miles - 4.6 miles
Distance remain = 3.4 miles
Speed of hike = Distance remain / Total time remain to travel
Speed of hike = 3.4 / 2
Speed of hike = 1.7 miles per hour

What is the circumference of this circle?
Answer:
12.56
Step-by-step explanation:
its really 12.57 but yeah
Step-by-step explanation: To find the circumference of
the circle shown here, start with the formula c = 2πr.
Since the radius is 2 km, we can plug is 2 km for r in the formula.
So we have (2)(π)(2 km) which is equal to 4π km.
Now, remember that π is approximately equal to 22/7 or 3/14.
So we can estimate the value of the
circumference by plugging in 2.14 for π.
So we have (4)(3.14) which is equal to 12.56.
So the circumference is approximately equal to 12.56km.

The area of a trapezium is 550 cm2 and the length of the parallel sides is 23cm and 27cm, find the distance between them.
Answer: 22 cm.
Step-by-step explanation:
Formula for area of trapezium: [tex]Area = \dfrac12 (\text{Sum of parallel sides})\times \text{(Distance between them)}[/tex]
Given: Area = [tex]550\ cm^2[/tex]
Length of parallel sides : 23 cm and 27 cm
Let h=distance beteen them.
then
[tex]550=\dfrac12 (23+27)(h)\\\\\Rightarrow\ 550=\dfrac12(50)h\\\\\Rightarrow\ 550=25h\\\\\Rightarrow\ h=\dfrac{550}{25}\\\\\Rightarrow\ h= 22[/tex]
Hence, the distance between them = 22 cm.
parallel and perpendicular
Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right 90 degrees angle
