Answer:
120 ways
Step-by-step explanation:
To solve the question above, we use combination formula:
Where ;
nCr = n! / (n-r)! r!
10C7 = 10! / (10 - 7)! 7!
10C7 = 10! / 3! 7!
10C7 = (10 * 9 * 8) / 3 * 2 * 1
10C7 = 720 / 6
= 120 ways
3m(a-2b)+(a-2b)^2
= 3m(a-2b)+(a-2b)(a-2b)
= (a-2b)(3m+a-2b)
A net with a square base and 4 triangular side
-24 = -0.6k
k=-24/-0.6
k=40
