+5x−3
Step-by-step explanation:
2x
2
−x+6x−3
2x
2
+(−x+6x)−3
Rewrite it in the form a^2 - b^2, where a = 2x and b = 5
(2x)^2 - 5^2
Use the Difference o Squares: a^2 - b^2 = (a + b)(a - b)
<u>(2x + 5)(2x - 5) </u>
Right next to the zero van I heht brainleist please
To find the acceleration of the bicycle rider, we are going to use the acceleration formula:

where

is the acceleration

is the initial speed

is the final speed

is the time
We know from our problem that increases his speed from 5 m/s to 15 m/s in 10 seconds, so his initial speed is 5 m/s and his final speed is 15 m/s; therefore,

,

, and

. Lets replace those values in our formula:



We can conclude that the acceleration of the bicycle rider 1 m/s^2
