You will need data that logs the changes in speed from various, consecutive events. Which you can use to calculate the difference in speed and determine wether the speed is increasing or increasing.
Otherwise, you only need the initial and finak value to find the difference.
Answer:
4x - 16
Step-by-step explanation:
X can be any value (I made it 20)
5.5(2)+ 1 - (1.5(2) +17)
11 + 1 - 20
12 -20
-8
4(2) - 16
8 - 16
-8

Answer:
a) 2.5×2.5×2.5-1.4×1.4×1.4=12.881
b) (2.5)2+2.5×1.4+(1.4)2=31.5
Step-by-step explanation:
yuh multiple 2.5 three times and subtract 1.4 multiple three times. 2.5×2.5×2.5-1.4×1.4×1.4
15.625-2.744=12.881.
b) when opening bracket Yuh multiple the number in the bracket by the number outside the bracket. when bracket is open Yuh can now add, multiple to obtain your answer please
(2.5)2+2.5×1.4+(1.4)2
5+2.5×1.4+2.8
7.5×4.2=31.5
In order to factor, we must pull out factors common to each term. In this case, each term has factors of 2 and y:
4ay =
2 * 2 * a *
y
2y =
2 *
y
So, we'll pull out the 2y:

To check, distribute the 2y back through the terms in parentheses to ensure you end up with the original expression 4ay - 2y.
