Q1, The answer is <span>B. plus or minus the square root of 60
x</span>² = 60
x = ?
Since a² = -√a or a² = +√a, then
x = -√60 or
x = +√60
Q2. The answer is <span>C. 2.83 inches
The area of the square (A) with side s is:
A = s</span>²
Since A = 8 in², then s² = 8 in²
s = √8 in²
s ≈ 2.828 in
s ≈ 2.83
Q3. The answer is <span>D. plus or minus 11
</span>
x² = 121
x² = 11²
Since a² = -√a or a² = +√a, then
x = -√11² or x = +√11²
x = -11 or x = + 11
Hope you find an answer to this problem it's actually pretty hard
Answer:
k = 5x - 42
Step-by-step explanation:
Answer:
Step-by-step explanation:
We have total 1200 wildflowers in first year that is first term a is 1200
We have to find sigma notation showing the infinite growth of the wildflowers.
Formula for infinite sum of GP is 
Here, 
On substituting the values in the formula of sum we get:
On simplification we get:
Therefore, total sum of wildflowers 1600.
22 because 6 inches on top and bottom means you need 12 inchesw each drape and you have 4 drapes so 48 inches therefor rounding that you get 1 yard each added onto the 8 feet and 5 feet for each drape.
