Answer:
To find the height of a cube you simply need to know the length of the sides of a cube.
Step-by-step explanation:
All sides of a cube are equal because it is made up of squares. If a cube has a length of 3 cm, then it will also have a height of 3 cm.
4(2x+1) = 3(x+8)
8x + 4 = 3x + 24
5x = 20
∴x = 4

Answer:
No, this isn't a right triangle.
Step-by-step explanation:
First of all, the hypotenuse is the longest side (in this case that is 50), so that's what we're working for.
The formula for the Pythagorean theorem is :
14 squared equals 196, and 28 squared equals 784. Add these and you get 980. The square root of 980 is not 50, so we know that this is not a right tryangle.
Answer: The difference in temperature is -44 degrees.
Explanation: Since the new temperature is a negative number and the old was positive, you add them together. However instead of (-5) +39 (which the answer would be 35), you would write 5 +39 because -5 is 5 spaces away from 0. You can also check by using the equation 39 -44. You would get the answer -5, proving that the answer is indeed -44 degrees.
