Answer:
here I worked it out on my calculator so it should be right
5 root 11
Answer:
18,720
Step-by-step explanation:
there are approximately 52 weeks in a year
(sorry if it's too late and you've already figured it out, but here you go anyway)
The easiest way to do this is to start by FOILing then add.
So just start with (x-1)(x-1)
(x-1)(x-1)
Front: (x*x) = x^2
Outer: (x*-1) = -x
inner: (-1*x) = -x
Last: (-1*-1) = 1
Added: x^2 -2x +1
Now take that answer and do the same thing with (x-1). It's basically the same thing, just with an added thing you need to multiply.
(x-1)(x^2-2x+1)
(x*x^2) = x^3
(x*2x) = 2x^2
(x*1) = x
(-1*x^2) = -x^2
(-1*-2x) = 2x
(-1*1) = -1
Now add everything together:
x^3+2x^2+x-x^2+2x-1
The answer is:
x^3+x^2+3x-1
To solve these type of problem you have to make the denominator the same or use the claculator.
let us do this problem by making the denominator the same.


So, now. the one with the largest numerator is the largest fraction
In this case,

is the largest which is equal to

.
So, the largest fraction is

.
Answer:
The approximate area is 35 square centimeters
Step-by-step explanation:
we know that
The cross section passing through the diagonal of opposite faces of the cube is a rectangle
so
the approximate area is equal to

where
b is the diagonal of a face
h is the length side of the cube
we have

substitute
