Thank you sly!! 100%
Sly is correct!!!
An estimate for negative square root of 93 is ____.
[-(sqrt(93))] If its an imaginary just apply absolute value
Find perfect squares close to 93.
9^2 = 81
10^2 = 100
Find the difference between the squares and 93. (The smaller the value the closer it is to the root of the square.)
100 - 93 = 7
93 - 81 = 12
So, the first answer is D.) -9.5
Test taking strategy: Use the answer options and square them.
9.1 * 9.1 ~= 82
9.5 * 9.5 ~= 90

A Square's Area is the length of one side multiplied by itself. This problem has the same approach given for the first question.
Find perfect squares close to 52.
7^2 = 7*7 = 49
8^2 = 8*8 = 64
Find the differences. (Smaller is better)(Make sure the differences are positive numbers.)
53 - 49 = 4
64 - 53 = 11
So 7FT is closer.
Here is a table for x^2.
SQUARES
1^2 = 1
2^2 = 4
3^2 = 9
4^2 = 16
5^2 = 25
6^2 = 36
7^2 = 49
8^8 = 64
9^2 = 81
the answer
For the first question, estimating the negative square root of 93 requires finding the closest whole number to the actual square root of 93. The square root of 93 is approximately 9.64. Since we want the negative value, the estimate would be -9. Therefore, the correct answer would be C-9.1.
For the second question, to find the approximate length of one side of Julie's garden, we need to find the square root of the given area of 52 square feet. The square root of 52 is approximately 7.21. However, since we need to find the approximate length, we can round the square root to the nearest whole number, which is 7. Therefore, the correct answer would be B: 7FT.
Based on the explanations provided, your answers for the questions are both correct.
