Answer:
30
Step-by-step explanation:
z = 7√2 cos(7/8π) + 7√2i sin(7/8π) = 7√2e^(i7/8π)
Round to the nearest fraction and find a number to divid that go into the top and bottom number
Answer:
x={-5,-6}
Step-by-step explanation:
x²+11x+30=0
x²+5x+6x+30=0 (as 5*6=30 and 5+6=11)
x(x+5)+6(x+5)=0
(x+5)(x+6)=0
so
x+5=0
x+6=0
therefore
x=-5
x=-6
