Answer:
y = 4(x+6)(x-2)
Step-by-step explanation:
y = 4x² + 16x - 48, factor out the 4
y = 4(x² + 4x - 12), find factors of 12
Factors of 12:
1*12, 2*6, 3*4; find a pair that sums to 4x or 4
6-2 = 4, since 12 is a negative number, a number in the factor must be negative, in this case, making 2 negative, would make 6-2 = 4
y = 4(x+6)(x-2)

Answer:

Step-by-step explanation:
Biquadratic Equation
It's a fourth-degree equation where the terms of degree 1 and 3 are missing. It can be solved for the variable squared as if it was a second-degree equation, and then take the square root of the results
Our equation is

If we call
, our equation becomes a second-degree equation

Dividing by -3

Factoring

It leads to these solutions

Taking back the change of variable, we have for the first solution

Now for the second solution, we get imaginary (complex) values

Summarizing, the four solutions for x are

Answer:
1.
Mean: 65
MAD: 6.4
2.
Mean: 60.5
MAD: 6.4
3. The diference of the means are 4.5
I’m sorry, I do not understand the last one.
Step-by-step explanation:
The mean is the average, add all of the values and divide the result by the number of values. The MAD is the mean absolute deviation. You find it by taking the distance between the values and the mean. You then add them together and divide it by the mean. I really hope this helps you!
