Answer:
B 24
Step-by-step explanation:
3/5 is 54°
1/3 is 30°
54-30 = 24
Radius is just half of a diameter. and you just multiply the diameter by pi for circumference.
so here, it would be 35x2 x 22/7 so the answer is 220 CM
Answer:
The answer is zero
Step-by-step explanation:
y = x² - 4x + 8
4x + y = 12
4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
x² + 8 = 12
- 8 - 8
x² = 4
x = ±2
4x + y = 12
4(2) + y = 12
8 + y = 12
- 8 - 8
y = 4
4x + y = 12
4(-2) + y = 12
-8 + y = 12
+ 8 + 8
y = 20
(x, y) = (2, 4) and (-2, 20)
