We know that the major axis of the ellipse is 12 ( 2 a = 12 ).An ellipse is a curve with 2 focal points, such that the sum of the distances to the 2 focal points is constant for every point on a curve.If P is a point on a curve:PF 1 + PF 2 = 2 a( Blue line ) + ( Red line ) = 2 a = 12Answer: The sum of the lengths of the red and blue line segments is 12.
Answer:
376.81
Step-by-step explanation: 376.81
1) (-4 . x) + (-4 . 3) = 8
-4x - 12 = 8
-4x = 20
x = 20/-4
x = -5
2) 3 = (3/4 . b) + (3/4 . -8)
3 = 3/4b - 6
3 + 6 = 3/4b
9 : 3/4 = b
3 . 4 = b
12 = b
3) (1/6 . p) + (1/6 . 24) = 10
1/6p + 4 = 10
1/6p = 6
p = 36
4) 3/5 . a + 3/5 . 5,25 = 7,35
3/5a + 3,15 = 7,35
3/5a = 4,2
a = 7
All 3 angles of a triangle add up too 180, so 80+55= 135, 180-135 is 45, so the value of x is 45
20% of 50 = 10 , 45% of 200 is 90. 35, 2 4.5
