You need 10 logs for 1 brick. To get 10 bricks you need 100 logs. You are collecting stones and 1 stone gets you 4 logs. That means to get 100 logs you’ll need 25 stones. That indirectly means that 25 stones gets you 10 bricks.

This shape is made of three identical semicircles.

Answer:

48cm

Step-by-step explanation:

The perimeter of first shape is 36cm. There are 3 semi circle (curves).

Therefore,

3 curves of semicircle (arc length) = 36

1 curve of semicircle (arc length) = 36/3

= 12cm

In picture 2,

4 semicircles (They've mentioned that they used the same semicircle for the 2nd shape also)

So,

4×12 = 48cm

Multiply (x^3 + 3x^2 + 3)(3x^3 − 6x^2 − 8x + 1)

When multiplying two equations like this, you need to distribute. Distribute each term to get 3x $x^{6}$ + 3 $x^{5}$ − 26 $x^{4}$ −14 $x^{3}$ −15 $x^{2}$ −24x+3
