Answer:
e = 10
Step-by-step explanation:
9e+4=-5e+14+13e
Combine like terms
9e+4=14+8e
Subtract 8e from both sides
9e-8e+4=8e-8e +14
e +4 = 14
Subtract 4 from each side
e+4-4 = 14-4
e = 10

</span>12a^3b = 4ab(3a^2)
8a^2b^2 = 4ab(2ab)
20ab^3 = 4ab(5b^2)
GCF = 4ab
12a3b + 8a2b2 − 20ab3 = 4ab(3a^2 + 2ab - 5b^2)
