Remember
ab+ac=a(b+c0
3x+3x+5+5
2(3x)+2(5)
2(3x+5)
2nd option
The answer is C. Use the quadratic formula to solve it and you should be just fine!
The dog snored nine times. 1/3 of an hour is every 30 minute interval. 30 min + 30 min = 1 hour. Multiply this x3, and the answer is nine. A simpler way of thinking about this is 3 x 3 or 3 squared.
-12y+14-9y=14
-21y=0
y=0, x=7
