Answer:
A= 20,58m²
Step-by-step explanation:
the side opposite to what is worth 6m is the diameter of the half circle to the left. I calculate the circumference of the circle (diameter multiplied by π), so 6 × π = 18.84
since the circumference is not whole but only half, we divide the result in half: 9.42 (the length of the half circle).
formula for the area of the rectangle: base multiplied by the height all divided by 2: (10×6)/2= 30m²
we subtract half the circumference: 30-9,42=20,58m²
Answer: The answer is x^2+2xy+2y^2–3x–3y–1
Step-by-step explanation: Move 2 to the left of y^2.
Answer:
k(qq)/r^2 times the length of the distnace
Step-by-step explanation:
Force times distance. The Electrical force is the only thing you have to find first.
Step-by-step explanation:
the first one is 2 that appears most while the second is 20 and 3
So
(x-4)^2=(x-4)(x-4)=x^2-4x-4x+16=x^2-8x+16
