Answer:
m=-2 n=-6
Step-by-step explanation:
(z+1+i)(z+1-i)=z²+2z+1-(i²)=z²+2z+2
z³+mz²+nz-8=(z²+2z+2)(z-4)=z³-2z²-6z-8
m=-2
n=-6

Answer:
1240 in³
Step-by-step explanation:
The overall dimensions of the block are ...
10 in by 11 in by 17 in
The volume of that space is ...
V = LWH = (10 in)(11 in)(17 in) = 1870 in³
The volume of each of the three identical holes is similarly found:
V = (10 in)(3 in)(7 in) = 210 in³
Then the volume of the block is the overall volume less the volume of the three holes:
= 1870 in³ - 3(210 in³) = 1240 in³
