You are travelling 65 miles in 1 hour, or 60 minutes.
So 65 miles in 60 minutes
And x miles in 22 minutes
We can solve the following for x to get the answer

Hope that helps. :)
Recall that the equation to find the perimeter of a rectangle is 2(L + w)
Since we know the length, we can make an equation:
2(3 + w) = 12
Divide both sides by 2:
(3 + w) = 6
w = 3
Now that we know both length and width, we simply have to find their product to solve for area:
a = L * w
a = 3 * 3
a = 9
The area of the rectangle is 9 cm^2.
672,591 is rounded to 700,000.
<u>z²-2i=0</u>
Answer:
Solution given:
z⁴=-4
doing square root on both side

we know i²=-1
substituting i² we get
z²=
z²=2i
z²-2i=0 is a required answer. where
z² and 2 is real number.
