Elan Coil [88]

Answer:

$\boxed{\bold{4x^2\left(6xy^2-y+21x^2\right)}}$

Step By Step Explanation:

Apply Exponent Rule $\bold{\:a^{b+c}=a^ba^c}$

$\bold{x^4=x^2x^2,\:x^3y^2=x^2x}$

$\bold{24x^2x-4x^2y+84x^2x^2}$

Rewrite 84: $\bold{21\cdot \:4}$

Rewrite 24: $\bold{6\cdot \:4}$

$\bold{6\cdot \:4x^2x-4x^2y+21\cdot \:4x^2x^2}$

Factor Out Common Term $\bold{4x^2}$

$\bold{4x^2\left(6xy^2-y+21x^2\right)}$

➤ $\boxed{\bold{Mordancy}}$

Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions.
By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then

a = 220 (t)
b = 220 (t) + 220 (.25)

And we want to know when these two equal eachother, as that's they will both detonate.

220t = 200 t + 200 (.25)
20t = 50
t = 2.5

V initial = 0
v final = 1920 m/s
t = 3 2/3 mins = 220s

d = 1/2(vi + vf)t
d = 1/2((0)+(1920))(220)
d = 211200m
