Answer:
the area of the house shaped thing is 60m and the area of the circle is 25.748
Step-by-step explanation:
to find the area of the house thing, you find the area of the triangle base×height divided by 2, which is 20. then you find the area of the rectangle 8×5= 40, add them together to get 60.
to get the area of the circle you do diamer×pi 8.2×3.14= 25.748
Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0
Divide both sides by 2:
x^2 - 2 x - 3/2 = 0
Add 3/2 to both sides:
x^2 - 2 x = 3/2
Add 1 to both sides:
x^2 - 2 x + 1 = 5/2
Write the left hand side as a square:
(x - 1)^2 = 5/2
Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)
