AB = X^2(3X +2)
C^2 = (x - 3)^2
AB - C^2 = 3x^3 + 2x^2 - (x^2 - 6x + 9)
= 3x^3 + x^2 + 6x - 9
Answer:
P= 20x+2 ft
Step-by-step explanation:
________
I I
I I 3x + 7ft
________
7x - 6ft
P= (7x - 6 + 7x - 6) + (3x + 7 + 3x + 7)
= (14x - 12) + (6x + 14)
= 20x + 2 ft
Answer:
216°
Step-by-step explanation:
Both chords are the same length, so the left and right arcs are both 72°. The whole circle is 360°, so:
72° + 72° + x = 360°
x = 216°
