Answer:
It would be the first one.
Step-by-step explanation:
When it says "at least" that means Kristen has to walk 20 miles at minimum, but she can walk more if she chooses to. Therefore in context of the problem, the greater than or equal to sign would work best.
diagonal = sqrt(a^2 +b^2)
20 = sqrt(12^2 +b^2)
20= sqrt(144+b^2)
20^2 = 144 + b^2
400 = 144 + b^2
256 = b^2
b = sqrt(256) = 16
it is 16 inches wide
2 dollars a pound for strawberries 3 dollars a pound for blueberries
The answer is C. X^2-6x+9
