Answer:
Substitute the w‘s in the equation for 2.
8(2)^2+8(2)+9
32+16+9
57

Answer:
at least above 3$
Step-by-step explanation:
Step-by-step explanation:
Distance = rate × time
If B is the rate of the boat, and C is the rate of the current, then we can write two equations:
18 = (B + C) × 3
18 = (B − C) × 9
Simplifying the equations:
6 = B + C
2 = B − C
Add the equations together to eliminate C:
8 = 2B
B = 4
Plug into either equation to find C:
C = 2
The boat's rate is 4 mph, and the current's rate is 2 mph.
Um well lets see there is no question so the day that ends in y
It would be 40. youd just add a zero to the end of each number and they add up to 250
