Total length of the board = 2.5 meters
= (2.5 * 100) cm
= 250 cm
Let us assume the length of the first shelf = x
Then
Length of the second shelf = 2x + 18
Length of the third shelf = x - 12
Length of the fourth shelf = x + 4
Now we can easily get the equation as
x + 2x + 18 + x - 12 + x + 4 = 250
5x + 10 = 250
5x = 250 - 10
5x = 240
x = 240/5
= 48 cm
length of the second shelf = 2x + 18
= 2(48) + 18
= 96 + 18
= 114 cm
So the length of the second shelf is 114 cm.
The answer to your problem would be -8
I got this because if you take 4 - 2x to the third power, it would look like this:
(4 - 2x)^3
All you have to do it plug in 3, solve for the equation in the parentheses, and then take that number to the third power. In this case, you get -2, and if you take that to the third power, you get -8.
Hope this helps!
Turn them into improper fractions
44/2 divided by 11/4
Divide = multiply reciprocal
44/2 * 4/11 = 176/22 = 8
The answer is 8
The area of the circle is πr², ie. 144π.
The volume of the cilinder is 12×144π = 1728π cm³.
I vote for answer A.
The slope of that line is m=2/5
