Answer:
X1=-4+4i
X2=-4-4i
Step-by-step explanation:
X^2+8x+32=0
Δ=b^2-4ac=8^2-4(32)=-64<0
X1=(-b-i√Δ) /2a=(-8-8i)/2=-4-4i
X2=(-b+i√Δ) /2a=(-8+8i)/2=-4+4i

Answer:
5 cm
Step-by-step explanation:
The kite is symmetrical about the long axis, so the height of each of the triangles is half the overall width of the kite. (10 cm/2 = 5 cm)

1) 7 hours and 33 minutes
2) 28
3) y = 7
4) a times a times a times a
6 times (7+5) plus 3 or 6x(7+5)+3
