Answer: quadrant III
Step-by-step explanation: srry if am wrong
I got it its this answer i used mathpapa for this
Step-by-step explanation:
x=width of pool
2x=length of pool
the dimensions of the rectangle forming the walkway and the pool are x+4 and 2x+4
the area of this rectangle minus the area of the pool is 196 square feet
(2x+4)(x+4)-(x)(2x)=196
2x^2+4x+8x+16-2x^2=196
combine similar terms
12x+16=196
12x=196-16
12x=180
x=180/12
x=15 feet is the width of the pool
check: 34*19-30*15=196
646-450=196
196=196
3x(2x+3y)
1. find a common multiple of either sides of the + sign...
3x
2. put it outside the brackets...
3x( )
3. find what you have to multiply the rest equation by to get the number...
2x x 3x = 6x squared
3y x 3x = 9xy
4. put it in the brackets...
3x(2x+3y)
Hope this helps :)
