Answer:

Step-by-step explanation:
The sum of interior angles of a 5-sided polygon is 540 degrees.
We sum all the angles to get:
<M+<L+<N+<O+<P=540
90+90+(17x+4)+(18x+6)+(10x-10)=540
45x+180=540
45x=540-180
45x=360
x=8
N=18*8+6

Let the side lenght of cube is a
voluem of cube= 0.008
a^3=0.008
a =0.2
side of lenght is 0.2
Step-by-step explanation:
2008because there is no difference between the number of sold notebooks
3x=14-5
3x=14-5
3x=9
x=9 ➗ 3
x= 3
the answer is 3
