X^2 = 4x + 12
x^2 - 4x - 12 = 0, use the quadratic equation
Solve for x over the real numbers:
(x - 6) (x + 2) = 0
Split into two equations:
x - 6 = 0 or x + 2 = 0
Add 6 to both sides:
x = 6 or x + 2 = 0
Subtract 2 from both sides:
Answer: x = 6 (or x = -2 only positive solution)
Answer:
x = 148
Step-by-step explanation:
The angles shown are vertical angles.
Vertical angles are congruent ( equal to each other )
Because vertical angles are equal to each other x = 148
To calculate the mean absolute deviation, you first must find the mean of the data and then find the difference between each piece of data and the mean.
Please see the attached picture for the work.
The mean absolute deviation is approximately 1.48.
This means that the numbers of candies in the 10 bags are all very close to one another. There is not much variation.

Hope This Helps :)
62.50 x (0.07 x 125)
0.07 x 125=8.75
62.50 + 8.75=71.25
She can afford it.
I am sure, about the answer but not the equation
