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
Hope this helps!

Answer:
WX = 107
Step-by-step explanation:
The sum of the segment lengths is the overall length.
37 +WX = 144
WX = 144 -37 . . . . . subtract 37
WX = 107
Answer:
y=2x-4
Step-by-step explanation:
slope=2=k
y-intercept in - 4 then n=-4
y=kx+n
y=2x-4
The answer is a whole number, and it happens to be 1
