cheers
Perfect. Short, pithy and unequivocally 100% correct.
5r+1=a(m+r)
5r+1=am+ar
5r-ar=am-1
r(5-a)=am-1
r=(am-1)/(5-a)
BTW I'm an accountant, so if you want a different answer, just let me know (it'll cost though)
AB is 4cm
CD is k cm longer than 4cm
BC is square root of 3 cm
The area of trapezium is 5 multiply square root 6 cm squared
calculate k in form a root b - c where a b amd c positive intergers
AB=4cm
BC=root 3 cm
CD=k cm longer than AB
DA is a slope up to A

Imagine kids googling it and discovering a betting forum!

Haven't done quadratic equations in 30 years. Had to Google how to do them
A ______4_____ B
/l l
/ l 1
/ l l root 3
/ l 1
/____l__________l
k
D X C
Area ABCD given as (5 x root6) squared
Area ABCX = 4 x root3
Area AXD = (5 x root6 squared) - (4 x root3)
Area AXD = (k x root3)/2
therefore (k x root 3)2 = (5 x root 6 squared) - (4 x root3)
so you can solve the value of k by just doing the above calc.
(I reckon)
If you want me to show it as an expression though, it'll cost (I'm an accountant and former management consultant so can't do it all for free)
Fookin Betfair.
But I think you can still make it out.
If you want it again it's £10

Its not everyday someone solves 4 variables using one equation. You deserve some award for this my friend.
That would explain it if he is.
If not apologies
