Answer:
5
Step-by-step explanation:
If you use the quadratic formula you get -8 and 5 the answer is either of these.
Answer: Width = 6 ft, length = 18 ft
Step-by-step explanation:
If the width is w, then the length would be 3w.
3 * 3w * w = 324
9w^2 = 324
w^2 = 36, since w is positive it has to be 6.
So, the width = 6 and the length = 18.
Answer:
The answer is 3x+6
Step-by-step explanation:
You multiply what's on the outside of the parenthesis by everything on the inside, so you would do 3 times x and 3 times 2. They don't combine because they are like terms.
The coordinates of U after the reflection are: (-5, -3)

How to get the coordinates after the reflection?</h3>
By looking at the graph, we can see that the coordinates of point U are:
U = (-1, -3)
And we want to reflect it across the line x = -3.
Notice that because this is a vertical line, the y-component does not change by the reflection. Only changes the x-component, such that the distance between the original coordinates and the final coordinates to the line don't change.
The original x-component is x = -1, the distance to the line is:
d = |-3 - (-1)| = 2 units.
Then the new x-component will also be at 2 units of the line, but in the other direction:
new x-component: x = -3 - 2 = -5
The coordinates of U after the reflection are:
(-5, -3)
