Answer:
- 4 - 5i
Step-by-step explanation:
The centre of the circle is the average of the endpoints
centre = (- 2 + i - 6 - 11i ) ÷ 2
= (- 8 - 10i ) ÷ 2
= - 4 - 5i
Q=(c+d)/2
Multiply both sides by 2 to get rid of the 2
2×q=(c+d)
Subtract c from both sides to get rid of the c
2×q-c=d
Flip the equation around
d=2×q-c
Answer:
0.2
Step-by-step explanation:
Answer:
g = 5
Step-by-step explanation:
Expand brackets.
4g - 2 = 3g + 3
Add -3g and 2 on both sides.
4g - 3g = 3 + 2
Combine like terms.
1g = 5
Answer:
see explanation
Step-by-step explanation:
(3x - 1)(x + 5)
Each term in the second factor is multiplied by each term in the first factor , that is
3x(x + 5) - 1 (x + 5) ← distribute parenthesis
= 3x² + 15x - x - 5 ← collect like terms
= 3x² + 14x - 5
