The number furthest to the right (with decimals) is always the most uncertain digit to being smaller than the number on the left. The more decimals, the more accurate the measurement is. In this case the number "2" is the most uncertain.
Hope this helps! A thanks/brainiest answer would be appreciated :)
Answer:
this can be solved by simple unitary method
Answer:
9 + x
Step-by-step explanation:
The area of a rectangle is length times width.
A = lw
We know the area is 81 - x^2 and the width is 9 - x, so plug them in.
81 - x^2 = 9-x * w
81 - x^2 is a difference of squares in the form a^2 - b^2 = (a-b)(a+b), so we know the width must be 9 + x.
Test it to be sure:
(9 + x)(9 - x)
81 + 9x - 9x -x^2 = 81 - x^2
It works!
