First use distributive property:
4(5x - 6) - 4(2x + 1)
20x - 24 - 8x - 4
Then add like terms:
12x - 28
<u>Answer:</u>
- A: (Negative 3 and one-half, 2 and one-half)

Answer:
1 hour 42 minutes
Step-by-step explanation:
Given: Speed of 1st trucker= 62 mph
Speed of 2nd trucker= 66 mph
Total distance need to cover to be in contact is 270 miles
1st trucker start 1 hour ahead of 2nd trucker
Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.
We know, distance= 
1st trucker, distance
∴ 
2nd trucker, distance
∴
Now, putting the values in an equation.
⇒ 
Opening the parenthesis to solve and subtracting both side by 62
⇒ 
∴ x= 
= 1 hour 42 minutes
∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.
Answer: 60 cm three squared
You can observe in the picture attached that the box is a rectangular prism.
The volume of a rectangular prism can be found with this formula:
Where "l" is the length, "w" is the width and "h" is the height.
You know that the lenght of each side of those cubes is 1 centimeter. Therefore, you can multiply the number of cubes on each side of the box by 1 centimeter in order to find the lenght, the width and the height of the box:
Now you can substitute the lenght, the width and the height of the box into the formula shown at the beginning of the explanation:
Finally, evaluating, you get that the volume of the box is:
223 units
