By solving for x you get x=6
First you need to find the surface area of the wall that was painted, and then add the additional area in the hallway that was painted.
The wall that was painted was 9 feet by 10 feet, or 90 square feet. 90 square feet plus the additional 46 square feet in the hallway is 136 square feet, which is the total area that the paint covered.
Therefore the solution is 136 square feet.
Answer:
x = 
Step-by-step explanation:
Given expression is,
x =
Slope of segment here = 4/8 = 1/2
slope of perp needs to equal -2
midpoint of segment = (3,-1) so include that as a point:
y = -2(x-3)+1
(y- (-1)) = -2(x-3)
First you need to find the rule or 'equation' that this system goes by before we can solve what H' point is located.
So, to do so, label out the triangles points:
A(-7, 6), B(-5, 3), C(-1, 3) to A'(1, 4), B'(3, 1), C'(7, 1)
Now for A to A' which is -7 to 1 is a 8 point difference and A to A' which is 6 to 4 is a -2 point difference, indicating:
(x + 8, y - 2)
Now:
B(-5, 3) -> (-5 + 8, 3 - 2) = B'(3, 1)
C(-1, 3) -> (-1 + 8, 3 - 2) = C'(7, 1)
Now to simply solve for H to H':
We know H 's coordinates are: (-7, -5)
Now add in the rule and solve:
(-7 + 8, -5 - 2) = ?
Answer: (1, -7)
