Answer:
96
Step-by-step explanation:
first off you know that it is a square pyramid, so you can assume that all base lengths are 6.
i am going to find the base first. it is 36 because 6*6-36 save this in your mental memory
next, we have to find the 4 triangles
we know that they are 5 by 6 but you have to divide them by 2
so 30/2=15 and there are 4 of them
15*4=60
now add together 60 and 36 and you get 96
hope this helps!

Answer:
Let y=x² . Then:
x4−10x2+9=y2−10y+9
y²-10y+9=(y-9)(y-1)
Substitute x² for y:
x4−10x2+9=(x2−9)(x2−1)
x²-9=(x+3)(x-3)
x²-1=(x+1)(x-1)
x4−10x2+9=(x+3)(x−3)(x+1)(x−1)
Answer:
1246 teams
Step-by-step explanation:
We are told there are 7women & 6men.
If 5 people are selected and there must be more women than men in the team.
This means there must be a minimum of 3 women.
Thus;
For 3 women;
7C3 × 6C2 = 525
For 4 women;
7C4 × 6C3 = 700
For 5 women;
7C5 × 6C0 = 21
Thus;
Total = 525 + 700 + 21 = 1246 teams
