Answer:

B) (x-1)2+(y+1)2= 25 radius = 5 miles

Step-by-step explanation:

Equation of a circle:

(x - h)² + (y - k)² = r²

(h,k) = (1, -1)

r = 5

(x - 1)² + (y - -1)² = 5²

(x - 1)² + (y + 1)² = 25

Multiply (2x + 2y)(2x + 2y)
Maslowich

Answer:

4x² + 4y² + 8xy

Step-by-step explanation:

( 2x + 2y ) ( 2x + 2y ) = ( 2x + 2y )²

Formula : -

( a + b )² = a² + b² + 2ab

Here,

a = 2x

b = 2y

( 2x + 2y )²

= ( 2x )² + ( 2y )² + 2 ( 2x ) ( 2y )

= 2²x² + 2²y² + 8xy

= 4x² + 4y² + 8xy

What is the remainder of (3x^4+2x^3-x^2+2x-14)/ (x+2)
Allisa [31]

Hi,

I assume the forward slash meant it as a fraction VS it being a division symbol. To answer your question, the remainder is 10.

Hope this helps.
