The differnce of 2 perfect cubes
remember
a³-b³=(a-b)(a²+ab+b²)
so
Answer:
The answer should be 45
Step-by-step explanation:
To get the whole are you would have to multiply the lenght with the Width and then take that answer and multiply it with the height
<u>BUT</u>
because you want the surface area, it would be just the lenght and width
15x3=45
so 45 is your answer.
Answer:
k = 324
Step-by-step explanation:
Y varies inversely as x
Let k be the constant of variation
Y = k/ x
Y= 36 and x= 9
Substitute the value of Y and x
36 = k/9
Make k the subject of the formula
k= 36*9
k =324
Answer:
<u><em>The original price would be 50$.</em></u>
Step-by-step explanation:
To find this answer you have to divide 25% by 100, which equals 0.25. Now multiply 0.25 by 40 and you get 10$. Since 10$ was the discount, you just add 10$ + 40$, therefore 50$ is the original price.
Answer:
Step-by-step explanation:
x^3 = 1/8
Taking the cube of both side
x^3 = 1/(2)^3
(x)^3 = (1/2)^3
Eliminate ^3 from both sides
x = 1/2
