Answer: How fast was she going per hour? 12.5 miles.
#2 is 2.7 hours in 4.5 miles
Step-by-step explanation:
So, since it is square, we are going to take the square root of 121 which is 11. And since fencing goes around something, that means we have to find the perimeter. So since all four sides are the same length, we can just multiply 11 by 4 to get 44 meters of fencing

Answer:
C. 4 +√(x+5)
Step-by-step explanation:
The sign between the terms changes to form the conjugate. The radical contents are unchanged.
The conjugate of 4 -√(x+5) is 4 +√(x+5).

<em>Additional comment</em>
The utility of a conjugate is that the product of a number and its conjugate is the difference of two squares. The squares are intended to remove an undesirable feature of the number, its imaginary part or its irrational part, for example. Here, the product of the number and its conjugate would be ...
(a -b)(a +b) = a² -b²
4² -(√(x+5))² = 16 -(x +5) = 11 -x . . . . no longer contains a root
Answer:
1/6
Step-by-step explanation:
There are 6 numbers on a dice
1,2,3,4,5,6
the even numbers are 2,4,6
so there are 3/6 chance of getting an even number
3/6=1/2
5 and 6 are the two numbers greater than 4
so there are 2/6 chance of getting a number greater than 4
2/6=1/3
So for both to happen chance = 1/2 × 1/3
= 1/6
