Answer:
j = -8
Step-by-step explanation:
-13j - 20 = -8j + 20
Add 13 j to each side
-13j+13j - 20 = -8j+13j + 20
-20 = 5j+20
subtract 20 from each side
-20-20 = 5j +20-20
-40 = 5j
Divide by 5
-40/5 = =5j/5
-8 =j
Answer:
C
Step-by-step explanation:
x^3+4x^2-9x-36=0
or x²(x+4)-9(x+4)=0
or (x+4)(x²-9)=0
or (x+4)(x+3)(x-3)=0
x=-4,-3 or 3
