Answer:
144
Step-by-step explanation:
i just did the test
The line is an upside U shape from A to B
This means the graph increases, then decreases.
20+8x=50
x=50-20 Subtract the numbers
8x=30 Divide both sides of the equation by
x= 15/4 final answer
hope i helped :)
Answer:
x=11
Step-by-step explanation:
Please see attached image.
Let length, width, and height be s.
Then diagonal of any face would be √( s² + s² ) = √( 2s² )
And we know that it measures √( 500 ) so that's sufficient for us to figure out the length of an edge of the cube. We do not need to worry about the diagonal of the cube.
Now we have to solve √( 500 ) = √( 2s² )
Square both sides:
500 = 2s²
Divide both sides by 2:
250 = s²
Take the square root of both sides:
√(250) = s ≈ 15.8113883
Rounding to nearest tenth:
s ≈ 15.8
Final answer: 15.8
Hope this helps.
