b is the correct answer
Step-by-step explanation:
see the step in the picture
<span>(4d-4)(3d-2)=12d^2 + []d + 8
Using FOIL method:
4d x 3d = 12d^2
4d x -2 = -8d
-4 x 3d = -12d
-4 x -2 = 8
Adding common terms, we have:
-8d + -12d = -20 d
The missing coefficient is -20.</span>
Y = ln |1 + t - t^3| = (1 - 3t^2)/(1 + t - t^3)
Answer:
90 units
Step-by-step explanation:
circumference C = 2
r
taking
as 3.
C = 2 × 3 × 15
(15 is the radius of the circle)
C = 90 units
