The answer is 22 because in order to divide fractions (in this case we would have 11 as a fraction), you need to multiply one fraction by the reciprocal of the other fraction (the flipped form of a fraction).
To find this, we would do
*
.
This would come to be
, and when simplified by dividing the numerator and denominator by 9, you get 22.
Answer:
x + 5
Step-by-step explanation:
A = LW
W = A/L
W = (x^2 + 16x + 55)/(x + 11)
W = [(x + 11)(x + 5)]/(x + 11)
W = x + 5
Right triangles must follow the pythagorean theorem, so a^2+b^2=c^2.
Let's find a^2 and b^2 by squaring the first 2 side lengths.
(x^2-1)^2= x^4-2x^2+1
(2x)^2= 4x^2
Then add the two to find c^2
x^4+ 2x^2 +1= c^2
Root both sides
x^2+1=c
Since the side lengths can be plugged into the pythagorean theorem, the side lengths must represent a right triangle.
Hope this helps!
If there are 5 specific spots and the order does matters then we would have:
11*9*8=792
Hope this helps!
