I could be wrong but I got 28. I devided 420 by 15
Area of square/rectangle = length times width
The answer should be 4. Take note of the pattern of unit digits of 2^n.
2^1 = 2
2^2 = 4
2^3 = 8
2^4 = 16
2^5 = 32
Every 4 powers, it rotates 2, 8, 6, 4. Since 2020 is divisible by 4, the answer is 4.
Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (3, 4 ) and (x₂, y₂ ) = (8, - 3 )
m =
=
= -
