40 miles x 5,280 feet per mile = a lot a lot divided by 60 minutes divided by 60 seconds = 58.67 feet per second
An expression of the second degree can be any kind of expression, the most popular being a quadratic polynomial of the form ax^2 + bx + c.
You need to convert the minutes into seconds so that the units match. 1 minute = 60 seconds 20 minutes = 1200 seconds speed = distance travelled divided by the time taken so- speed = 1000m divided by 1200s speed = 8.333m/s
substitution
100 divided by 25 times 64 = 256
2.2 meters per second.

"Divide the first number by the second number." "Find the quotient when the first number is divided by the second number." "Separate the total into equal parts based on the second number."
The reciprocal of any expression is 1 divided by that expression. In this case, the reciprocal of x2 is 1/x2. This can also be written as (1/x)2, or as x-2.
Its speed was 15cm per second. ( 75cm divided by 5 seconds = distance per each second, which is essentially an expression of speed).
40 miles x 5,280 feet per mile = a lot a lot divided by 60 minutes divided by 60 seconds = 58.67 feet per second
Let N represent the 'number'. It looks like the first phrase would be expressed as 2(N + 5) which expands to 2N + 10, while the second expression would be 2N + 5, which is not the same.Notice that the first one is 2 times the sum, while the second is 2 times a number.
Physicists believe it can be divided into approx 1.855*10^43 parts. Each part would then represent a Planck unit of time.

It's 32 + 24
what is the coefficient of the second term in this expression- 5 - mn - n
