Answer:
62 cm
Step-by-step explanation:
Given the expressions for width (3x + 1) and length (5x - 2) as well as the formula for the perimeter of a rectangle: 2(5x - 2) + 2(3x +10), we can first solve for the simplified expression of 'x' and then substitute the given value of x = 4cm to find the total distance:
Distribute: 2(5x - 2) + 2(3x +1) = 10x - 4 + 6x + 2
Combine like terms: 16x - 2
Plug in '4' for 'x': 16(4) - 2 = 64 -2 = 62 cm
Speed = distance / time
7 = 17.5 / t
t = 17.5 / 7
= 2.5 minutes
Step-by-step explanation:
2a - 7 - 6a = 9
- 4a - 7 = 9
- 4a = 16
a = -4

Answer:
To provide a situation of 1 and O, here is a situation
Step-by-step explanation:
The acceleration would be 1.
If the acceleration is 10 m/s, the object will gain more speed.
On the other hand, if the acceleration is -10m/s, then the object will lose speed.
In the case of 1, the object gained more speed, in the case of 0, the object will lose speed.
