Answer:
x = -4
Step-by-step explanation:
Subtract x^2-16 from both sides:
x^2 +8x +16 = 0
(x +4)^2 = 0 . . factor
x +4 = 0 . . . . . take the square root
x = -4
The one real solution is x = -4.

<em>Additional comment</em>
As you can see from the factoring, the root has multiplicity 2.
The slope of a vertical line is 0
Hope this helps!
Answer:
The true statements are;
1) The line containing points A and B lies entirely in plane T
2) Line z intersects plane S at point C
3) Planes R and T intersect at line y
Step-by-step explanation:
1) The points A and B are located on the line v which can be found on the plane T
2) As shown on the diagram, the line z, that has points C and D, passes through the plane Z at the point C
3) The intersection of the planes R and T is the line y. This is so because, the intersection of two planes can be seen as a line that is along the area of their intersection.
The garden does form a right triangle.
Answer:
The answer is x=35
Step-by-step explanation:
Right Side:
First we convert . This result in .
Left Side:
We can convert the left side the same way:
Both Sides:
Since both sides have the same base, we can set their exponents equal to each other.
4x-5 = 3(x+10).
At this point we can solve for x normally and get x = 35.
