the answer is 3
but a way to work these problems out is to use PEMDAS
p-parentheses
e-exponent
m-multiplication
d-division
a-addition
s-subtraction
they have to be donr in that order or the answer will come out different
z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
Y = -5x + 12 since the slope of that line is -5x and in order to pass through that point the y intercept must be 12
1. To answer this question we must keep on mind that we already have the distance from Cleveland to Cincinnati.
2. They tell us that it is 40 centimeters on the first map.
3. If on the first map
then:

4. Then the distance from Cleveland to Cincinnati is 400 kilometers.
5. On the second map 
6. Then we want to know how many centimeters represents 400 kilometers on the second map. Therefore:

The answer is: 8 centimeters.
2/5 will be shaded in the original how I got it s that you make a rectangle and make fifths inside and shade in 3/5 of that and see what matches up on the top.
