Answer:
ab/(a+b)
Step-by-step explanation:
Without loss of generality, we can put point C at the origin and define line BD by the equation ...
x/a +y/b = 1
Points (x, y) fall on the line BD, and we have point L where x=y. That value of x, the square's side length, will satisfy ...
x/a +x/b = 1 . . . . . fill in x=y in the equation
x(a+b)/ab = 1 . . . .factor out x, add 1/a+1/b
x = ab/(a+b) . . . . solve for x
The length of the side of the square is ab/(a+b).

Product means the answer to multiplication problems.
so 7/2 = 3.5 then 3.5/2 = 1.75
(1.75 * 2) = 7/2
Answer:
35
Step-by-step explanation:
We need to factor by grouping. Group xy with -4x and 2y with -8 and factor each group.
(xy-4x)+(2y-8)
x(y-4)+2(y-4)
b. (x+2)(y-4)
Hope that helps.
