Any number that is divisible by 4 is also divisible 8 counter example

1 answer:

7 0

The simplest example would be 4. 4 is divisible by 4, but not by 8, since $\dfrac44=1\in\mathbb Z$ , but $\dfrac48=\dfrac12\not\in\mathbb Z$ . (The quotient needs to be an integer)

A rectangle with an area of 47 m² is dilated by a factor of 7. What is the area of the dilated rectangle?

MA_775_DIABLO [31]

We already know that the area of the rectangle increased by a square of the factor 7. So the dilated area of it (which we will call "Ad"), is:

Ad= (47)(7^2)
Ad= 47x49
Ad= 2303 m^2

What is the area of the dilated rectangle? The area of the dilated rectangle is 2303 m^2.
