A rectangle has an area of 36 inches squared. Write an equation to show how the length (l) varies inversely the width (w).

1 answer:

8 0

Start with the first sentence, and the definition of the area of a rectangle:
l * w = 36

Rewrite the equation to get
l = 36 / w
or
w = 36 / l
Either one shows the inverse relationship between w and l.

Assuming the last part wants you to write an equation for an x-y graph, the equation would be
y = 36 / x

What is the square root of 18 plus the square root of 2? And is it rational or irrational?<br>

kicyunya [14]

The answer is (rounded to the nearest tenth) about 5.7 and since neither 18 or 2 have a perfect square, so this is irrational.
