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

C=a/bd
Only if parallelogram is in the form of a rectangle will AC equal BD because a square is not a parallelogram.

a(c+d)+b(c+d)=(a+b)(c+d)
Because it can be derived from a large number of more basic principles applied to numbers. Since a/b and c/d are defined, then b and d are non-zero. Then a/b = ad/bd since multiplying the numerator and denominator of a fraction by a non-zero number leaves it unchanged. Similarly, c/d = bc/bd [These steps implicitly assume the commutative property of multiplication ie there is no difference between premultiplication and postmultiplication] Another property of numbers: If x = p and y = q then x+y = p+q [equals added to equals result in equals]. So a/b + c+d = ad/bd + bc/bd and finally, using the distributive property of multiplication [by 1/bd] over addition, = (ad + bc)/bd Maybe you wish you hadn't asked!
If AC equals 6 and BD equals 4, then AB equals 5.
BD = 5x + 3Subtract 3 from each side:BD - 3 = 5xDivide each side by 5:1/5 of (BD - 3) = x
(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
A = (1/2)(ac)(bd) = (1/2)(8)(9) = 36
C=a/bd
ohh jeeeze!!!!!! lol

ba=(16/(16+8))bd=(16/24)bd=(2/3)bd area of the rectangle = bd*bf area of triangle = (2/3)bd*bf/2=(1/3)*bd*bf 1/3
