Write at least four rational numbers between -2/5 and -1/3.

-0.34, -0.35, -0.36, -0.37

Step-by-step explanation:

A rational number can be any number, negative or positive, so long as if the decimals (if any) terminate at some point or at least repeats itself.

- = -0.4

- = -0.333_ (This means that the digit "3" is repeated forever)

Thus, the possible rational numbers can be:

-0.34

-0.35

-0.36

-0.37

-0.38

-0.39

You can even write decimals like -0.334 since it is bigger than -0.333_ but smaller than -0.4.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
