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).
11 + 3x = −15 − 4x
U subtract 11 from both sides 11+3x-11=-15-4x-11
Refine3x=-4x-26
Add 4x to both sides
3x+4x=-4x-26+4x
Refine7x=-26
Divide both sides by 7
<span>7x/7 = -26/7</span>
Refinex= -26/7
Answer:
42 cannot be divided into 926 .. however 926 can be divided by 42 and the answer will be 22.04 rounded of to 22
so your answer is: 22
3x-8=-3+2x
x-8=-3
x=5
the number is 5 hope this helped (:
