<em>x</em> ² - 4<em>x</em> + <em>y</em> ² + 8<em>y</em> = -4
(<em>x</em> ² - 4<em>x</em> + 4) + (<em>y</em> ² + 8<em>y</em> + 16) = -4 + 4 + 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 16
(<em>x</em> - 2)² + (<em>y</em> + 4)² = 4²
which is the equation of a circle centered at (2, -4) and with radius 4.
Answer:
i think its the 3 line. they are congruent.
Hey there!!
Given equation :
11x² + 35x + 6
Now let's write 35x as 33x and 2x
Then the equation would become :
... 11x² + 33x + 2x + 6
... Now, let's take the common terms 11x² + 33x and 2x + 6
It would become :
... 11x ( x + 3 ) + 2 ( x + 3 )
... Now, we will write this as :
... ( 11x + 2 ) ( x + 3 )
Hence, this is as the answer...
Hope my answer helps!!
Area of the 3 rectangles that make up the prism:
30 * 25 + 30 * 17 + 30 * 28 = 2100
Area of the two triangles at either end:
Use bh/2
(15 * 28)/2 = 210
There are two so it’s 420
2100 + 420 = 2520cm^2
