sum means addition, so just add the three numbers...
12.6 +3.1 = 15.7 + 5.4 =21.1
21.1 is greater than 20
What I think you should do is that you multiply 99 and 82 degrees and divide that answer with 110 and you get z. Than for y is 99.
I don't know if it's right but that I think you should do.
Answer:
Step-by-step explanation:
Let the original side is x.
1 foot = 12 inches
<u>New sides of a rectangle are:</u>
<u>The area of rectangle is:</u>
<u>Solve for x:</u>
- x² + 8x - 48 = 960
- x² + 2*4*x + 16 - 64 = 960
- (x + 4)² = 1024
- x + 4 = 32
- x = 28
<u>Area of the original blanket:</u>
The given equation for the relationship between a planet's orbital period, T and the planet's mean distance from the sun, A is T^2 = A^3.
Let the orbital period of planet X be T(X) and that of planet Y = T(Y) and let the mean distance of planet X from the sun be A(X) and that of planet Y = A(Y), then
A(Y) = 2A(X)
[T(Y)]^2 = [A(Y)]^3 = [2A(X)]^3
But [T(X)]^2 = [A(X)]^3
Thus [T(Y)]^2 = 2^3[T(X)]^2
[T(Y)]^2 / [T(X)]^2 = 2^3
T(Y) / T(X) = 2^3/2
Therefore, the orbital period increased by a factor of 2^3/2

Answer:
One of these numbers is a cube number which means that it could be 1,8, or 27 because those are the first three cube numbers.
If you go with one then you have to find two more numbers that add up to 35 and are a factor of 20, which is not possible.
Then you use 8, which means you have to find two numbers that add up to 26, and are factors of 20, which could be nothing, there aren't any.
Last you do 27 which means you need to find two numbers that add up to 9 and are factors of 27, which can be 4 and 5, because 4+5=9 and 4*5=20.
27,4,5
Hope this helps ;)
