Answer:
First one--4x³ + 17x² - 19x - 20
Step-by-step explanation:
1. To solve for a you need to take out any variable that is with it. F=ma, so divide by m on both sides to get F/m=a.
2. Use the previous formula/equation for this. Plug in the numbers, so -25/10=-2.5 units.
3. You're looking for the mass, so you do the same thing to the previous formula. F=ma, so divide F by a to bring it to one side, isolating m. F/a=m, plug in numbers, 25/5=5 units.
Answer:
sorry i dont know
Step-by-step explanation:
6 dollar divided per 8 lemons = $0.75
If you let x represent the width of the rectangle, then you can write the equation for area as
.. x(2x +5) -63 = 0
This has positive solution x=4.5.
The rectangle is 4.5 meters by 14 meters.
