Since 4i is a root, that automatically means -4i is also a root (complex roots always travel in pairs) So the factored form would look like (x+4i)(x−4i). When multiplied out this gives the polynomial x2+16.

Find the measure of ∠C if

V125BC [204]

$(32x+20) + (72x+20) + (52x+40) + (32x+10)=180 \\ 32x+72x+52x+32x +20+20+40+10 =180 \\ 188x+90=180 \\ -90 \\ 188x=90 \\ /188 \\ x=0.478
$
then $52(0.478)+40 \\ 24.856+40=64.856
$
∠C = 64.856

1 5/6 divided by 11/12

deff fn [24]

First convert the mixed number to a fraction: 1 5/6 = 11/6.
$\frac{\frac{11}{6}}{\frac{11}{12}}=\frac{11}{6}\times\frac{12}{11}=2$
