The region is made up of
• a right triangle with short leg 10 m and hypotenuse 26 m
• a parallelogram with sides 40 m and 26 m (the 26-m side corresponds to the aforementioned hypotenuse)
• another triangle with two known legs of length 20 m and 26 m
Find the height of the right triangle using the Pythagorean theorem. If the height is h, then
(10 m)² + h² = (26 m)² ⇒ h² = 576 m² ⇒ h = 24 m
This height is common to all three shapes.
Now find the area of each shape.
• right triangle:
1/2 × (10 m) × (24 m) = 120 m²
• parallelogram:
(40 m) × (24 m) = 960 m²
• other triangle:
• 1/2 × (20 m) × (24 m) = 240 m²
Then the total area of the shaded region is 1320 m².
x+y=5
-x -x
Equals:
y=-x+5
Now you have:
y=-x+5
x-y=1
Insert -x+5 into y
x-x+5=1
Combine like terms
2x+5=1
Subtract 5.
2x=-4
Divide 2.
Answer: x=-2
Answer:
-6
Step-by-step explanation:
We are given that -x-10y=2 is a true equation so by multiplication property of equality, we can multiply everything by -3 on both sides. This gives us 3x+10y=-6
Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
