Answer:
(6, -4) does not fit with these two equations
Step-by-step explanation:
y = 8 - 2x
x + 3y = 12
fit (6, -4) into the equations
-4 = 8 - 2(6)
8 - 2(6) = 8 - 12 = -4
works for this one
6 + 3(-4) = 12
6 + 3(-4) = 6 - 12 = -6
doesnt work for this one
The answer will be CCCCCCCCC
Answer:
$520.96
Step-by-step explanation:
This is a compound shape made of 1 rectangle and two semi circles which makes 1 full circle.
Area of Rectangle = L x W
Area of circle is =pi x radius squared
Area of Rectangle is 5ft x 4ft = 20 ft squared.
Area of circle is = 12.56 ft squared
- Diameter of the circle is 4ft, radius is 1/2 diameter
- Radius is 2ft, 2 x 2 = 4ft
(pi) 3.14 x 4ft = 12.56 ft squared.
As it is a compound shape you need to add
Area of Square + Area of circle =
20 ft squared + 12.56 ft squared =
Total Area of window is 32.56 ft squared
$16 = 1 square foot
$16 × 32.56 = $520.96
