You add half of the coefficient of x and square it.
What you do on one side,you must do it on the other.
Answer:
The side length is 9 m
Step-by-step explanation:
The area of a square is given by
A = s^2
81 = s^2
Take the square root of each side
sqrt(81) = sqrt(s^2)
9 =s
The side length is 9 m
9514 1404 393
Answer:
A. Initial value 12, rate of change -2
Step-by-step explanation:
We note that the x-values in the table go up by 1 and the y-values go down by 2. That "down by 2" for "up by 1" is the rate of change: -2/1 = -2.
If we extend the table upward one more row, we have x=0 and y=12. That is, the "initial value" is 12.
The initial value is 12; the rate of change is -2.
