Answer:
A rectangle has a length 6m less than twice its width. when 5 m are added to the width, the resulting figure is a square with an area of 256m^2. find the distance of the original rectangle
width:: x
length:: 2x-6
-------
New width:: x+5
---
Equation:
(x+5)^2 =256 =16
16 is the original length
We're told that
where the last fact is due to the law of total probability:
so that and are complementary.
By definition of conditional probability, we have
We make use of the addition rule and complementary probabilities to rewrite this as
By the law of total probability,
and substituting this into gives
Volume of cube equals side^3
therefore 12 to the power 3 equals 1728 cm cubic

Answer:
65 cm²
Step-by-step explanation:
(10 x 10) - (5 x 10)/2 - (2 x 10)/2 = 100 - 25 - 10 = 65
