Answer:
look its really simple like if there is written the father age is two times than its son and its is also said sum of their age becomes 25 then
Step-by-step explanation:
solution,
let father and son age be x and y
2x =y ---------------(i)
x+y=25----------------(ii)
now,
putting the value of y in equation two we get,
x+(2x)=25
3x=25
x=25/3
x=8 yrs ( using round off)
again,
2x = y
2×8=y
16=y
therefore, father age is 16 and son age is 8

The coefficient of the x-term is -3. Add the square of half of that.
.. (-3/2)² = 9/4 . . . . . . the number you need to add.
x² -3x +9/4 = (x -3/2)²
_____
If the x² term has a coefficient other than 1, you need to factor that out first and deal with the remaining binomial. For example,
.. 2x² -6x = 2(x² -3x)
For this you would need to add 9/4 inside parentheses to get
.. 2(x² -3x +9/4) = 2(x -3/2)²
Of course, to keep the original value, you would need to subtract 2*(9/4) outside parentheses.
.. 2x² -6x = 2(x -3/2)² -9/2

sorry but you're gonna need to add more info to this question to get an answer
I'm pretty sure the answer is B) 11c+8.5(c-46)=470
hope i help :)
