Answer:
After 15 minutes, they are moving apart at 8100 ft/sec
Step-by-step explanation:
Using the direct proportion
For the man, 4ft/sec
4ft -----1 sec
Xft ----- 60 x 15 sec
X = 3600 ft/sec
For the woman, 5ft/sec
5ft -----1 sec
Xft ----- 60 x 15 sec
X = 4500 ft/sec
After 15 minutes they are moving apart at 4500 + 3600 = 8100 ft/sec

Answer:
1. -2x+24
2. 3x+21
3. 5x-17
4. 3x²+12x
5. 18
Step-by-step explanation:
2. 3(x)+3(7)=3x+21
3. 5(x)+5(-4)+3= 5x-20+3=5x-17
4. 3x(x)+3x(4)=3x²+12x
5. 3(10)-12=30-12=18
