3) (x − 5)(x − 1)= x² -1x -5x +5= x² -6x +5
4) (x + 5)(x + 1) = x² +1x +5x+ 5x = x² +6x+5

Answer:
slope = - 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 3 ) and (x₂, y₂ ) = (4, - 5 )
m =
=
=
= - 
Each box had 100 blocks in it.
-- 1/5 of the blocks in one box = 100/5 = 20 blocks.
-- 1/5 of the blocks in the other box = 100/5 = 20 blocks.
-- Total number of blocks used = (20 + 20) = 40 blocks.
The answer is 3 ÷ 56 = 18 or Raul puts 18 balls in 3 bags.
