Answer:+3i or -3i
Step-by-step explanation:
±√(-36)=+√(-36) or -√(-36)
+√(-1)×√(36) or -√(-1)×√(36) √(-1)=i
+i×6 or -i×6=+6i or -6i
Dividing by 2 we get
+6i/2 or -6i/2=+3i or -3i

Answer:
Cost of one rocket = $1.5
Step-by-step explanation:
Given:
6 rockets and 11 bombs cost = $36.50
14 rockets and 8 bombs cost = $41
Find:
Cost of one rocket
Computation:
Cost of one rocket = x
Cost of one bomb = y
So,
6x + 11y = 36.50.....eq1
14x + 8y = 41......eq2
From eq1
y = [36.50 - 6x]/11
From eq2
14x + 8y = 41
14x + 8[36.50 - 6x]/11 = 41
x = 1.5
Cost of one rocket = $1.5
