Answer:
B
Step-by-step explanation:
<span>-1=3(w+14)-7
Use distributive property
-1=3w+42-7
Subtract 7 from 42
-1=3w+35
Subtract 35 from both sides
-36=3w
Divide 3 on both sides
Final Answer: -12=w</span>
Answer:
27 by 27
Step-by-step explanation:
Let the sides be x and y. The problem is essentially asking:
Given 2(x+y)=108, maximize xy.
We know that x+y=54. By the Arithmetic Mean - Geometric Mean inequality, we can see that 
. Substituting in x+y=54, we get 
, meaning that 
. Equality will only be obtained when x=y (in this case it will generate the maximum for xy), so setting x = y, we can see that x = y = 27. Hence, 27 is the answer you are looking for.

Step-by-step explanation:
P is the principal amount, $400.00.
r is the interest rate, 7.5% per year, or in decimal form, 7.5/100=0.075.
t is the time involved, 6 month period(s) time periods.
To find the simple interest, we multiply 400 × 0.075 × 3 to get that:
The interest is: $90.00
Answer:
This is a perfect cube.
The side length is 4.
Taking the cube root of the volume will determine the side length.
Step-by-step explanation:
We are told that:
A cube has volume 64 centimeters cubed.
The formula for the volume of a cube = s³
Where s = side length
Hence
64 cm³ = s³
We can find s by finding the cube root of both sides
Hence,
cube root(64) = cube root(s³)
s = 4 cm
Note that 64 is a perfect cube because 4 × 4 × 4 = 4³ = 64 cm³
Therefore, it can be concluded of the cube that:
This is a perfect cube.
The side length is 4.
Taking the cube root of the volume will determine the side length.
