Answer:
The second option, 3x^2(x+3)(4x+1)
Step-by-step explanation:
Factor out the common term, which is 3x^2
This then becomes 3x^2(4x^2+13x+3)
Factor the inside term and it becomes
(3x^2)(x+3)(4x+1)

Answer:
slope = 
Step-by-step explanation:
Calculate the slope m using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (- 4, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m =
=
= 
Answer:
Step-by-step explanation:
From the information on 60 students we write frequency distribution as
x 1 2 3 4 5 6 7 total
f 13 22 15 6 3 0 1 60
C 13 35 50 56 59 59 60
xf 13 44 45 24 15 0 7 148
x^2f 13 88 135 96 75 0 49 456
Mean = 2.67
Var = 445.92
Std dev = 21.21
I quartile = 2
III quartile = 3
20% have atmost 1
