Answer:
165/14
Step-by-step explanation:
(7-4) + 17 / -14 + 2 x 5
3 + 17/-14 + 2 x 5
3 - 17/14 + 2 x 5
3 - 17/14 + 10
165/14
(4x – 7)(16x^2 + 28x + 49) is equivalen to 64x3 - 343!
To do this problem you would first need to factor out a variable, which in this case I would want to do the first equation because it is isolated. Now the equations would look like this:
x = -2y - 1
4x - 4y = 20
Since we know that x is now equal to -2y - 1 we can plug it in to the x value in the second equation:
4 (-2y -1) - 4y = 20
-8y -4 - 4y
-12y - 4 = 20
-12y = 24
y = -2
Now that we know the y value plug the y value to one equation to find the x, I will be using the first equation
x + 2(-2) = -1
x - 4 = -1
x = 3
Solutions:
y = -2
x = 3
Rubik's Cubes! I love these things...
There are multiple methods to solving the Rubik's cube. My personal favorite (and the best if you are a beginner) is the F2L method, or First Two Layers. The first half is patterns and placement, the rest of F2L consists of algorithms. There are not enough characters allowed to tell you specifically how to solve the Rubik's cube. However, there is a guy on YouTube who very clearly explains specific methods over how to solve it. His name is Noah Richardson. He is probably one of the best at explaining the cube's complexity into easy to understand terms, for beginners.
Glad to see more people getting interested into the Rubik's Cube again!
Have a good one!
