Answer: (x - 2)(x + 2)(2x + 1)
Step-by-step explanation:
q p
f(x) = 2x³ + x² - 8x - 4
rational root theorem: so the possible roots are: +/- 1, 2, 4,
Let's try x = 2
2 | 2 1 -8 -4
| ↓ 4 10 4
2 5 2 0 remainder is 0 so (x - 2) is a factor
0 = (x - 2) (2x² + 5x + 2)
0 = (x - 2) (x + 2)(2x + 1)
The line represents a direct variation because it is horizontal.
The line does not represent a direct variation because it does not go through the origin.
The line does not represent a direct variation because –4(3) ≠ 4(3).
A line y= k x, represents a direct variation if ,
As,line passes through (-4,3) and (4,3).
Equation of line passing through two points is,
Given by the formula:
As, the line does not pass through origin , so the line passing through (-4,3) and (4,3) does not represent direct variation.
Option (C)=The line does not represent a direct variation because it does not go through the origin.
20/3 paces must he take to complete the routine.
The marching band begins at the 50-yard line of a football field and marches perpendicular to the 40-yard line.
Hence,
So when the tuba players travel 18 inches with each marching pace, the paces are:
50+30+40 / 18 = 20 / 3
So, the answer is 20 / 3 paces.
Here, Distance divided by speed equals steps.

the answer is 150 because you figure that 75 is 3/4 of 100. and 1/4 of 200 is 50. or you can do
.75*200=150
