Step-by-step explanation:
Answer:
a^3 - b^3.
Step-by-step explanation:
Area = length * breadth
= (a - b)(a^2 + ab + b^2)
= a(a^2 + ab + b^2) - b(a^2 + ab + b^2)
= a^3 + a^2b + ab^2 - a^2b - ab^2 - b^3
Note: the 4 middle terms cancel out. So the answer is
a^3 - b^3.
Answer: 240
Step-by-step explanation:
Let the missing number be represented by p
5% of p = 12, where 5% = 5/100
Therefore, we can rewrite the expression as:
5/100 x p = 12
= 0.05p = 12
Divide both sides by 0.05 to get the value of p
0.05p/0.05 = 12/0.05
p = 240
Therefore, 5% of 240 = 12
