Answer:
4 * (x + 20) = 350
Step-by-step explanation:
1. 4 times the sum of X and 20 equals 350
First, you must add x and 20, which gives you (x + 20)
2. 4 times the sum of X and 20 equals 350
Next, you must multiply it by 4, which gives you 4 * (x + 20)
3. 4 times the sum of X and 20 equals 350
Finally, you must add the answer to make a full equation, which gives you 4 * (x + 20) = 350
I’m not sure but it will most likely be 90 degrees!
Let's say you had the two numbers 12 and 3. They multiply to 12*3 = 36. Applying the square root leads to sqrt(36) = 6.
Therefore, the geometric mean of 12 and 3 is 6.
In general, the geometric mean between two numbers x and y is sqrt(x*y). You multiply first, then apply the square root.
If you are working with 3 numbers, you multiply them out like before, but you instead apply the cube root. With 4 numbers you multiply like normal, but this time you would use a fourth root, and so on. With n numbers, you'll apply the nth root.
Answer:
The range is [-1, ∞).
Step-by-step explanation:
The points where the graph of this function cut the x axis are at x = 2 and x = 4 , it opens upwards and has a minimum value.
It has a minimum value when x = (2 + 4) / 2 = 3.
When x = 3, f(x) = (3 - 4)(3 - 2) = -1.
So the range is all real values of x >= -1, or [-1, ∞)
