Because we have two values of x, we can set the two expressions equal to each-other.
x^2 + 6x + 9 = x + 3
Subtract x and 3 from both sides.
x^2 + 5x + 6 = 0
Now that we have all terms on one side, we can find the values of x.
Using the AC method, we can simplify this equation to (x + 2)(x + 3)
The solutions to the system of equations presented are:
<h3>x = -2, x = -3.</h3>
Answer:
He drives at 54 mph. He will get 108 miles if he drives at that rate for 2 hours.
Step-by-step explanation:
9 miles in 1/6 of an hour
9x6=driving speed of 54mph
54x2 is 108 miles

Answer:
36.9 m
Step-by-step explanation:
h(t) = -4.9t² + 25t + 6
At t = 3:
h(3) = -4.9(3)² + 25(3) + 6
h(3) = -44.1 + 75 + 6
h(3) = 36.9
After 3 seconds, the ball will have a height of 36.9 meters.
