Answer:

C = 20π cm

Step-by-step explanation:

If you want the "exact circumference," use π instead of the usual approximation 3.14 or 3.14159.

Here the circumference is C = 2π(10 cm), or C = 20π cm.

Simplify the difference. (4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Blababa [14]

Answer:

  2w^2 -7w-2

Step-by-step explanation:

(4w^2 – 4w – 8) – (2w^2 + 3w – 6)

Distribute the minus sign

(4w^2 – 4w – 8) – 2w^2 - 3w + 6

I like to line them up vertically

  4w^2 – 4w – 8

– 2w^2 - 3w + 6

-----------------------------

  2w^2 -7w-2
