Let
and
denote the Laplace transforms of
and
.
Taking the Laplace transform of both sides of both equations, we have


Eliminating
, we get

Take the inverse transform of both sides to solve for
.

Solve for
.

Taking the inverse transform of both sides, we get

Answer:
Step-by-step explanation:
∠DEF is congruent to ∠EFA
I think it’s x+1x^3... not sure if this helps
(3) 8
Step-by-step explanation:
Note that ∆ADE is similar to ∆ABC. As such, the ratios of their legs are equal. Also note that AD = AB + BD.
BC/AB = DE/AD
BC/10 = 12/(10 + 5) = 12/15 = 4/5
or
BC = 10(4/5) = 8
