Simple interest formula and solution attached.
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!
Im sorry I don't know the answer to the question
Answer:
1000 meters is 1 kilometer so...
At total he biked 6 kilometers, 200 meters
The external angle between the secants (20°) is half the difference of the intercepted arcs.
(75° - B)/2 = 20°
75° - B = 40°
75° - 40° = B = 35°
