They do not mean the same thing:
4 in 4000 stands for 4 thousands
4 in 400 stands for 4 hundreds
In this case:
You can see, that first '4' means 4 000, while the second one means 400, so the first one is 10 times greater.

Answer:
The require value for s is 24.
Step-by-step explanation:
We are given that the expression x² + sx + 144 and we have to make it a square of a binomial.
Hence, we have to find the value of s for this purpose.
Now, let us assume that (x + 12)² = x² + sx + 144
⇒ x² + 24x + 144 = x² + sx + 144
⇒ 24x = sx
⇒ s = 24
Therefore, the require value for s is 24. (Answer)
Answer:
C. -6, -5, 2, 5
Step-by-step explanation:
A couple things to remember:
1. Negative numbers are always less than positive values.
2. If a number is negative, the greater the absolute value is, the less the number itself is. For example, -100 is less than -10, and -57 is less than -50.
Now, using these rules, we can put the numbers in order.
The numbers given are: 5, -5, -6, 2.
We know that 2 is less than 5, and that negative numbers are less than positive numbers. So, using this, we can order the numbers in two ways:
1. -5, -6, 2, 5
2. -6, -5, 2, 5
We also know that if a number is negative, the greater the absolute value is, the less the number itself is. Therefore, we know that -6 is less than -5. So, the correct order is -6, -5, 2, 5.
Hope this helps!
Answer:
C. or 54
Step-by-step explanation:
Assuming we are trying to find r then you would get 3*44 because distance=speed*time so distance is for the 3 hour time is 132 miles. To find the reaming distance you do 240-132= 108 so then we know distance/time=speed so 108/2=54 so the speed is 54 mph
