Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
Answer:
x = 3
ST = 24
Step-by-step explanation:
if T is the midpoint then ST = TU
8x = 2x + 18 move like terms to the same side
8x - 2x = 18 subtract like terms
6x = 18 divide both sides by 6
x = 3 to find ST replace x with 3

Answer is C I hope it helps
Heya friend,
------------------------------------------------------
Let the digits at ones place be x. Then,
the digits at tens place = (8-x)
Original number = 10(8-x) + x
= 80 - 10x + x
= 80 - 9x
On interchanging the digits
new number obtained = 10x + 8-x
= 9x + 8
According to question,
New number - Original number = 18
9x + 8 - (80-9x) = 18
=> 9x + 8 - 80 + 9x = 18
=> 18x - 72 = 18
=> 18x = 18 + 72
=> 18x = 90
=> x = 90/18
=> x = 5
Hence, the digits at ones place is 5.
The digits at tens place = (8-5) = 3.
So, the original number is 35 and the new number is 53.
Thanks
