6+6=12
8+4=12
or if you mean algebraic equation:
6+x=12
x+4=12
Answer:
12m
Step-by-step explanation:
You can break this shape down into a square and a trapezoid. Frist you can find the area of the square by multiplying 2 by 5 to get 10. Then you would find the area of a trapezoid by doing Area = 1/2height(base1+base2). We can find the height by subtracting 5 from 9. (We do this because we know the side of the square is 5m) Therefore the height would be 4m. We know the bases are 2 and 4. From there you can plug those numbers in to the formula. Area=1/2 * 4 (2 + 4)
Area= 1/2 * 4 (6)
Area = 2(6)
Area = 12m
The standard equation of a circle is given by:

Where r is the radius and the center is located at (h, k).
Since the center is at (3, -5), we have h = 3 and k = -5.
Now, to calculate the radius, let's use the point (8, 7) in the equation and solve it for r:

Therefore the equation of the circle is:
Answer:
Value of x for fg(x)=gf(x) at <em>f(x) = 2x²</em> and <em>g(x) = x+1</em> is x = -1/4 .
Step-by-step explanation:
We have, f(x) = 2x² and g(x) = x+1
Now, f(g(x)) = g(f(x))
⇒ <em>2(x+1)² = 2x² + 1</em>
<em>⇒ 2( x² + 2x + 1 ) = 2x² + 1</em>
<em>⇒ 2x² + 4x + 2 = 2x² + 1</em>
<em>⇒ 4x = -1</em>
<em>⇒ </em><em>x = -1/4</em>
