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
The answer is: [C]: "43" .
___________________________________
Since, if one adds "5 odd integers together", the sum has to be an "odd number"; and choice, [C]: "43" , is the only "odd number" that is an answer choice given.

It would be b. If you combine -3x-5y and 3x+5y, the x's cancel out. That would be the variable.
Answer:
n = -2
Step-by-step explanation:
Step 1: Write equation
3 = -1.5n
Step 2: Divide both sides by -1.5
n = -2
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
3 = -1.5(-2)
3 = 3
Answer:
<h2>
18 , 20</h2>
Step-by-step explanation:
Let the numbers be x and y
Sum = x + y
Sum = one number + 20
Cancel equal terms on both sides of the equation.
Again,
Finding another number
Sum = other number + 18
Cancel equal terms on both sides of the equation
Hence, The two numbers are 18 and 20.
Hope this helps..
