A. 100/20
The distance in meters should be divided by the time in seconds to get the value of the distance in meters travelled in one second.
Answer:
(2x+3y)(2x-3y)
Step-by-step explanation:
a² - b² = (a + b)(a - b)
4x² - 9y²
= (2x)² - (3y)²
= (2x + 3y)(2x - 3y)
One example could be, 2 • (9x + 6y)
Answer:
unbiased
Step-by-step explanation:
it would be biased if you lets say survey the history club kids
Step-by-step explanation:
In ∆ABC, m∠B = 90°
Therefore ∆ABC is a right angled triangle with sides AB = 4 & BC = 3. AC is the hypotenuse.
Hence, by Pythagoras theorem:
