How is a plus b over a minus b equals c plus d over c minus d?
(a + b)/(a - b) = (c + d)/(c - d) cross multiply(a + b)(c - d) = (a - b)(c + d)ac - ad + bc - bd = ac + ad - bc - bd-ad + bc = -bc + ad-ad - ad = - bc - bc-2ad = -2bcad = bc that is the product of the means equals the product of the extremesa/b = b/c
DF equals 11 in FA equals 5 in Find AD?
The square root of 146
Dc equals 10 what is the valure of ad?
10/3
If AD equals 55 and BC equals 8x plus 7 what is the value of x?
x = 0.125 ( BC - 7 )
When does e equal?
well albert figured it out in 123 ad it equals mc2
How is a plus b over a minus b equals c plus d over c minus d?

What is the perimeter of parallelogram abcd with ad equals 10 units ab equals 8 units ac equals 12 units ed equals 4.5 units?
If abcd is a parallelogram, then the lengths ab and ad are sufficient. The perimeter is 36 units.
What is the perimeter of the rectangle ABCD when AD equals 3 and BD equals 5?
It is 16 units.
DC equals 10 What is the value of AD?
10/3
Dc equals 10 what is the valure of ad?
10/3
If bd does not equal 0 then a over b plus c over d equals?
If bd ≠ 0, then a/b + c/d (the common denominator is bd) = (a x d)/(b x d) + (c x b)/(d x b) = ad/bd + cb/db = ad/bd + cb/bd = (ad + cb)/ bd
