The equation that has the solution is 3x^2 - 10x + 6 = 0
<h3>How to determine the equation?</h3>
The solution is given as:
The solution to a quadratic equation is
By comparing both equations, we have:
-b = 5
b^2 - 4ac = 7
2a = 3
Solve for b in -b = 5
b = -5
Solve for a in 2a = 3
a = 1.5
Substitute values for a and b in b^2 - 4ac = 7
(-5)^2 - 4 * 1.5c = 7
Evaluate
25 - 6c = 7
Subtract 25 from both sides
-6c = -18
Divide by - 6
c = 3
So, we have:
a = 1.5
b = -5
c = 3
A quadratic equation is represented as:
ax^2 + bx + c = 0
So, we have:
1.5x^2 - 5x +3 = 0
Multiply through by 2
3x^2 - 10x + 6 = 0
Hence, the equation that has the solution is 3x^2 - 10x + 6 = 0

10. As 8x = 2x + 60. So x =10
You first -7 from both sides.
7 + 2x = 13
-7 -7
Then you divide that by 2.
2x = 6
/2 /2
To get x equal to 3.
x = 3
It is given in the question that a mile equals 1.609 km and the moon is 2,160 miles in diameter.
One mile is equal to 1.609 km. Therefore 2160 mile equals to
THerefore 2160 mile equal to 3475.44 km and hence the diameter of the moon is 3475.44km .
