Answer:
J. The equation has one real solution and two complex solutions.
Step-by-step explanation:
Complex solutions come in pairs, so there can only be an even number of them. So we can rule out G, H, and K.
To find the other roots, we can factor using either long division or grouping. To use long division, see the attached picture. To use grouping:
3x³ − 4x² + x − 10 = 0
3x³ − 6x² + 2x² + x − 10 = 0
3x² (x − 2) + (2x + 5) (x − 2) = 0
(x − 2) (3x² + 2x + 5) = 0
The other factor is 3x² + 2x + 5. The discriminant of this is (2)² − 4(3)(5) = -56. Since the discriminant is negative, the roots are complex.
For number 7.
Supplementary angles sum to 180.
2x+4x=180
6x=180
x=30
The two angles are 2x and 4x or 60 and 120
Answer:
Step-by-step explanation:
The perimeter of a circle is 2πr
r here is 7 so the perimeter of the full circle is 14π which is 43.9822972
But you only have half a circle, so 43.9822972 / 2 = 21.991148.
But now you have to add the 14 cm to it to close the half circle, so 21.991148 + 14 = 35.991148 or 36 cm
Answer: x<2
Step-by-step explanation:
9(2+3x)<72
2+3x<72/9
2+3x<8
3x<8−2
3x<6
x<6/3
x<2
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great rest of Black History Month! :-)

Answer:
Find the value of X in triangles by subtracting known angle measurements from 180 degrees. Since the value of all angles within a triangle must equal 180 degrees, if you know at least two angles, you can subtract them from 180 to find the missing third angle.
Step-by-step explanation:
