A=L•W
25/49=5/9•W
25/49=5/9•W
/ 5/9. / 5/9. (Divided by 5/9)
Answer- about .918 miles
Y=1/2x i think , cuz the rate of change is 1/2
We are going to calculate D=b²-4ac , if it less than 0 , the equation will not have real solutions
1. D=4²+4*2*12 positive 2 real solutions
2. 2x²-x-12=0
D=1²+4*1*12 positive 2 real solutions
3. 2x²+4x+12=0
D=16-4*2*12=16-96=-80 no real solutions , correct answer C
4. D=16-4*2*0=16 two real solutions
