x Margo's age
Jaun + Margo
(2x+5) + x = 29
3x = 24
x = 8, Margo's age. Jaun 21 2*8+5
And to check...
sum = 29
-3x^2-2x (+-)6=0
ax^2+bx+c
a=-3
b=-2
c= either positive or negative 6 (there is no plus or minus in your question.)

Answer:
1462.5
Step-by-step explanation
225 mph means of course 225 miles per hour
225 x 6 is 1350 and then you have to do 225/2 which is 112.5 to find what half of 225 is then you add 1350+112.5 to get 1462.5
