Answer: Between the numbers -2 and -3
Step-by-step explanation:
The negative square root of 5 will be slightly greater than 2 because the square root of 4 is 2 and 5 is greater than 2. The negative square root of 5 will not be greater than -3 because 3 squared is 9. So it has to be between -2 and -3.
Answer:
Step-by-step explanation:
y^2 -x^2=
y^2=9^2=81
x^2=2^2=4
81-4=77
Yes, in the sense that the new area could be written as (x+1)^2 / 1.
Usually we would not bother with the "1" as divisor.
Let's actually do the work: what is the area of the square if we increase the side length of the existing square by 1 ft?
(x+1)^2 = x^2 + 2x + 1 (This is not a fraction, and thus not the ratio of
two integers, which, in turn, is the definition of
"rational number."
