Step-by-step explanation:
7p³r² - 14pr³ = 7pr²(p²-2r)
Answer: 15x² + 2x + 4
x = -2/3, 0, 1/2
Step-by-step explanation:
5x(3x + 2) - 4(2x - 1)
First, distribute:
15x² + 10x - 8x + 4
Combine like terms:
15x² + 2x + 4
This is your polynomial!
If you needed to solve for x, take your original factored polynomial and set each term equal to 0:
5x(3x + 2) - 4(2x - 1)
5x = 0
x = 0
3x + 2 = 0
3x = -2
x = -2/3
-4 = 0
No solution
2x - 1 = 0
2x = 1
x = 1/2
x = -2/3, 0, 1/2

Answer:
$6.75
Step-by-step explanation:
Divide 33.75 by 5, they are $6.75 each
First convert the mixed numbers into fractions:
2 1/6 = 13/6
4 2/3 = 14/3
Now add the fractions:
13/6 + 14/3 = (13 + 14*2)/6 = (13+28)/6 = 41/6
Now convert it back to mixed number
41/6 = 6 5/6
thus 2 1/6 + 4 2/3 = 6 5/6
Hope it helps!
