Answer:

He would walk 4 blocks less if there were a straight path

Step-by-step explanation:

You need to use pitagoras in this one.

Noam goes north and east, forming a right angle. A direct path would close the other paths forming a right triangle. Knowing this, you can do:

8^2 + 6^2 = X^2

64 + 36 = X^2

100 = X^2

X = 10 blocks

You know that he walks 14 blocks (8+6) to school normally, so a direct path would be 4 blocks shorter

Vikki [24]

Answer:

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)

Step-by-step explanation:

(X^2 + x - 6) (2x^2 + 4x) =

Let's open the brackets carefully

x^2 * 2x^2 + x^2*4x + x*2x^2 + x*4x - 6*2x^2 - 24x

= 2x^4 + 4x^3 + 2x^3 + 4x^2 - 12x + 24x

= 2x^4 + 6x^3 - 8x^2 + 24x

= 2x ( 2x^3 + 3x^2 - 4x + 12)
